I could provide a macro to use emulated mutexes/conditions instead of 
native ones.

I don't Posix mutexes provide much robustness but they provide much 
higher performance, since emulation is based on atomic compare and 
exchange plus spin-waits.

Anyway, I definitely need some help on Mac OS 10.5. I don't know if 
anyway has used those process-shared mutexes in practice and if they 
work at all.
