Does this mean I can continue to leave the cron service running through 
a setup.exe upgrade as long as neither cygwin1.dll nor cyggcc_s-1.dll is 
being upgraded?  (Nor cron itself, obviously.)

I ask because the last time I ran rebaseall, it insisted I stop the cron 
service.

Yes, that should be possible.  You will find a list of DLLs which
couldn't be rebased in setup.log afterwards, but they are not
touched and rebase runs along.

Of course, this may have side effects.  Usually rebase packs the DLLs
side-by-side address-wise, so that they don't overlap and don't leave
holes in the memory layout.  In-use DLLs can hamper this effort so
there's a chance to leave holes.  And if, for some reason, two DLLs
are in use which overlap with each other, they will still overlap with
each other afterwards and can result in rebase problems subsequently.
Of course none of the rebased DLLs will overlap with the in-use DLLs.

Occassionally checking for overlaps with `rebase -si' doesn't hurt.
