  SVN rev 212077 on 2010-09-01 03:11:21Z by davidxu
  
  Change atfork lock from mutex to rwlock, also make mutexes used by malloc()
  module private type, when private type mutex is locked/unlocked, thread
  critical region is entered or leaved. These changes makes fork()
  async-signal safe which required by POSIX. Note that user's atfork handler
  still needs to be async-signal safe, but it is not problem of libthr, it
  is user's responsiblity.
