7u4 b11Fixed
Description
the asynchronous close functionality required on Linux/BSD oses is not working on Mac OS X yet. There are a few problems

1. The bsd_close.c code is not compiled in due to missing macro in net_util_md.h

2. NET_Accept is not using the BLOCKING macro

3. Interestingly, pthread mutexes must be explicitly initialized on Macosx and our code was not checking
   the return code of pthread_mutex_lock() which was failing silently and therefore not synchronising 
   properly and causing actual memory corruption and crashes.
Comments
EVALUATION Actually NET_Accept() uses NET_Timeout for its blocking. So, it can call accept() in a non-blocking way. Apart from that, the bug was fixed as in description.
