I have to apologize for my stupidity and rapid response. Forgive my lack of sleep. I was staring at the wrong spinlock.h.
Indeed, linuxthreads do end up calling sigsuspend() when they fail to acquire a mutex within a given time, and will/might receive a signal when the mutex becomes available again. So at this level, there is kernel level synchronization going on.
I need to think some more, obviously (!! :), about whether this is enough to ensure correct order scheduling of a threaded pipeline on an MP machine.
