that's why i started to implement a general fifo api according to the
paper by Dominique Fober, Yann Orlarey, Stephane Letz "Lock-Free
Techniques for Concurrent Access to Shared Objects"...
it implements a lock-free fifo queue, but requires to write assembler
(i haven't been able to implement it for ppc, since i'm not access one).
it might not be the first choice for single thread fifos, though...
i'm using the lock-free fifo for placing callbacks in the scheduler for
thread synchronisation, which is probably more powerful for thread
synchronisation than the current sys_lock(), since the synchronisation
won't run in the helper thread, but in the main pd thread...
cheers ... tim
