Do you see the patch kicking in, the "Found old pid..." message on stderr?

There is more to the story, see 
http://cygwin.com/ml/cygwin/2004-09/msg00812.html

Also it's not surprising that the current snapshot doesn't fully fix
the problem http://cygwin.com/ml/cygwin/2004-09/msg00813.html ,
increasing the pid reuse period only reduces the likelihood that
the problem shows up.
