The whole sequence number wakeup thing for condition variables is fundamentally broken in NPTL and needs to be fixed. Basically the issue is that the current code is over-engineered to avoid spurious wakeups, but in the process it suppresses some non-spurious wakeups... -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
