Summary: Problem with the kill builtin in MSYS bash

Initial Comment:
Hi!

I found an automake test that didn't behave properly (cont5.test). It
had a success rate of about 50% for me on MSYS. I have reduced it to
the attached simple test case, which fails much more often than the
original code.

I.e. start a process in the background, check if it is alive with
kill -0 (which it should be), and report failure if it isn't. But it
appears that kill fails if it is executed too soon after the new
process was created...

Now, I know that I'm not personally up to date, but someone
else stated that it also happens with up to date software.

$ sh --version
GNU bash, version 3.1.0(1)-release (i686-pc-msys)

$ uname -a

Message:
Thanks for the report and test case. I can reproduce it every time.

I believe I have found and fixed a race condition when determining if a
process is open.

Please try copying the following file over your existing msys-1.0.dll:

http://prdownloads.sourceforge.net/mingw/msys-1.0.dll.20100810?download

Does it solve the issue for you?

Regards,
Cesar
