Ok, that makes sense. Thanks :) I'm assuming RW_WRITE_HELD() and MUTEX_HELD() also only checks if it's held by the calling thread (I couldn't find any documentation on this, and the implementation of the RW_xxx_HELD() macros weren't very easy to understand :p) Oh well... now I only have to figure out a way to emulate this with POSIX threads.. :)
