Oder?
I can't speak for the boost implementation (haven't carefully studied it), but the Metrowerks implementation also supports conditions operating on a recursive mutex.
Interesting. I presume that this was a deliberate design decision.
It has a precondition "lock.mutex()->locked() && lock.mutex()-> lock_count() == 1" (or something like that... brrrr, so many "lock" things... "guard" would sound much better ;-) ) regards, alexander.
