I think that MS must have buggered up^W^W'improved' their scheduler between 2k and XP, and this interaction is a result. My first guess is that there's some competition for a locked resource of some kind, and this particularly interferes with scheduling under heavy load, but that's only a guess at the moment. I think tracking this one down might be easiest with a proper windbg/remote kernel debug setup. cheers, DaveK -- Can't think of a witty .sigline today.... -- 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/
