Or stay with the old versions. Wonder how this will affect postgresql. I'll report timings, when the new beta5 is out, 1-3 days.

But it could have been some other concurrency problem also. -- Reini Urban http://xarch.tu-graz.ac.at/home/rurban/ -- 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/
