we need to go a bit slower. For now i had to remove robust-futexes from the -rt17 release because they broke normal (non-robust) futex support in -rt15. A simple mozilla startup would hang... Please send fixes against -rt16 and i'll try to re-add the robust futexes patch later on. You can find -rt16 at: http://people.redhat.com/mingo/realtime-preempt/older/patch-2.6.14-rt16 > The previous patches only supported either file based pthread_mutexes > or mmapped anonymous memory based pthread_mutexes.
