I couldn't duplicate this on my main multithreaded windows system (which
is one of the reasons why I was hoping for someone else to step in and
help with the more obvious aspects of this debugging exercise) but I
could duplicate it on the "game computer". I discovered that the first
failing snapshot was 4/12. And, of course, that's the snapshot where I
put the windows command-line stuff back in for cygwin processes.
However, when deciding how small to make the windows command line
buffer, I chose too large a value for filling out the windows command
line for cygwin processes.
(see http://cygwin.com/ml/cygwin/2006-04/msg00534.html)
I've reduced the size of the windows command line which is sent to
Cygwin processes still further and that fixes the problem on my game
computer. That fact that this worked just fine on my normal test
computer (and presumably on Corinna's computer) is why this problem
crept back in. So, that leads me to believe that this problem is
system-dependent. I hope the constant that I chose is small enough
for all of the systems out there.
