First of all, yes I'm using cygserver.
I have uploaded an strace run of a gnome game (gnibbles) which shows the
symptom when pressing Help->Manual. The problem always occurs when a
gnome program starts another program like in this case gnome-help-browser.
There is also the corresponding cygserver debug output with comments
from me inline starting with ******
I do not find any fixup_shms_after_fork call in the strace, but there is
an open_shared call right in the beginning. I'm not sure it's the culprit

Maybe somebody can take a look.
