Thanks! Thinking about that a little more, getpriority(PRIO_PROCESS) returns the cached version of priority (since the last
setpriority()) but should return "live" version by re-getting and re-caching the actual thing from the system:
1. The priority could have been changed from the outside (it is a windows process, after all, and anybody can use Task Manager, for example);
2. When pulling group or user priorities from getpriority(), those things get returned from fresh "winpids", which gets constructed
on-the-fly and so "nice" gets populated from the system; so the results can be, again, inconsistent (e.g. if compared to getpriority() for
the process alone, since it is a cached one);
3. "/proc/PID/stat" always shows the live results (even before my change, although it was showing the "wrong" value).
Thoughts?

Feel free to provide a patch, just, please, create a valid git commit
message and send the stuff to cygwin-patches (unless the patch is
really trivial).
Thanks,

So, your commit message should have the form of:
"Subject line
Commit message"
A subject line is maximum 50 character long
A subject line starts in the imperative mode and does not end with any
punctuation marks.
The commit message is 72 character long.

Look at ch5 (distributed git), then .2 (contributing to a project),
then 'Public Project over Email'.
Also consult (using your Linux-box?)
- man git-format-patch
- man git-send-email
On Cygwin you have to install both git and git-email ... the latter
in case you want to use git send-email ...
Also, you will have to extend ~/.gitconfig in case you want to use
git send-email w/
[sendemail]
smtpserver = smtp....
smtpencryption = ...
smtpserverport = ...
smtpuser = ...
You were leaving town soon, were you not?
Good luck!

If you want to request for comment you could use 'git send-email' on
your own patch.
Basically, you need to familiorize yourself with 'git format-patch' and
'git send-email'.

Scratch the -a. This means `coommit all changes' and lazily replaces
the `git add' command. I screwed up here, sorry.

$ git add <files with changes you want to commit>
$ git commit -a
- opens editor to create a commit message. first line is summary,
second line stays empty, descriptive text follows in line 3+.
$ git format-patch -1
- creates a git patch file which can be attached to your email or
just send *as* email with `git send-email --to=<addr> <filename>
Starting with git has a bit steep learning curve, but it's totally
worth it. There's a great free online book available:

Well, that's just a quote from a former email. I would never have
recognized it as a commit message. A commit message should consist
of the one-line summary (in our case starting with the text "Cygwin: "
to distinguish the change from generic newlib changes), followed
by an empty line, followed by a descriptive text, what problem this
patch fixes and how.
Don't get me wrong, I'm glad you send patches, but it's tricky to create
a meaningful commit message if you're not the author of a patch. It's
also pretty time-consuming since you have to care for correct authorship
and stuff.
Thanks,
Corinna

Please educate me how to do that; I am just using "git diff --no-color".

git format-patch output with commit message, please? The commit message
should describe what the problem is and how the patch fixes it. One or
two sentences are enogh.
