I spent some time in the guts of the cygipc code, and think I tracked it down -- nothing was keeping the semaphore handles open but client processes, so when they all exited, the semaphore went away. I just posted a patch to fix this -- the ipc-daemon process now keeps semaphores open as long as they are supposed to exist. -- Joe Buehler -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
