Yes, it went unnoticed ;-)
the recursive_mutex constructor initialize/set/destroy the pthread_mutexattr_t every time. I'm wondering if we can improve the efficiency storing this on a static variable which will be initialized once. What could be the better way to initialize this static variable?
Note: the same applies to interprocess mutexes.
Storing static variables is tricky because of thread-race issues and mutex attributes usually are very lightweight (usually just setting some flags) so there is no much overhead with this. Regards, Ion
