Probably OT, but someone was complaining to me the other day that 
pthreads running on SCHED_FIFO/SCHED_RR that are blocked on mutexes 
don't release in priority order.  This was on a stock 2.6.18 kernel, 
"recent glibc" (I didn't catch which version or config), ARM9 platform.

First question: Is this actually true?

Second question: Does Xenomai fix this?  Do more recent kernel 
developments fix this?

Point me at the appropriate RTFM or code if that's the appropriate 
answer.  :)


Thanks,
