This idea was also mentioned here:
http://0pointer.de/blog/projects/name-your-threads.html

"So, now go, if you have a project which involves a lot of threads, name them
all individually, and make it easier to debug them. What's missing now, of
course, is that gdb learns this and shows the comm name when doing info threads."

Also note that glibc recently got support for getting/setting thread names for
Linux threads:

-thread-list-ids is deprecated, you should use -thread-info instead.

I am working on a patch to enable thread names.
