In the _THREAD_SAFE case, test for __isthreaded before calling the lock/unlock functions to try to save some performance. The _THREAD_SAFE case should become the default, but since it tests for a global variable in libc, people won't be able to build -current on pre-3.0 systems unless the default leaves it out. Such is life. END
