I still don't see the mmap issue but there may be some uses of naming
objects in cygwin that don't use shared_name(). I think I even
introduced one recently. If so, they should be fixed.
You're right that I didn't think about the potential mailing list issues
surrounding this. That's odd for me. I guess I should go to bed.
If this isn't generally useful, then I can just make this Red
Hat-internal. And, I'll send apologies to everyone for making you
think about this. I think that it may have some general use, though.
For instance, I'm now testing a "GNUpro" release on my W2K system and
find that I can't track down bugs in the net release because it
conflicts with the running compilation. This would alleviate that
problem.
So, this utility would be useful to cygwin developers at least.
However, I can see that people could try to use it to work around
release issues. Brr...
"I upgraded to cygwin 1.5.1 and found that I couldn't rsync my system
anymore so I moved rsync into a directory with cygwin 1.1.4 and used
cygisolate to run it. It works great except for the fact that I can't
find the files that rsync has copied to my system. What gives?"
