Comment (by waddlesplash):

 A first step would be attaching a debugger and determining what is waiting
 and where/why inside libroot's pthread_barrier.cpp.

 Actually, looking at that code briefly, I'm not sure why it uses the
 kernel mutex API directly, rather than using the user_mutex wrappers,
 seems a little strange. I guess because it needs to do
 B_USER_MUTEX_UNBLOCK_ALL?
