I just tried that testcase with Cygwin 1.7 and it appears to work most
of the time. Unfortunately I can still reproduce the problem once per
about 30 forks.
I'll look into fixing this for Cygwin 1.7. However, please note that
there is no *really* foolproof method to fix this due to the way fork
has to be implemented using Win32 calls. I can only make it much more
unlikely than today.

If you need to share memory only with forked processes, it's a much
simpler solution.

It's all in the announcement I referred you to.
