-/* Set up the mutexes for this file.  There are no races possible on
- * non-threaded perls, nor platforms that naturally don't have them.
- * Otherwise, we need to have mutexes.  If we have reentrant versions of the
- * functions below, they automatically will be substituted for the
- * non-reentrant ones.  That solves the problem of the buffers being trashed by
- * another thread, but not of the environment or locale changing during their
- * execution.  To do that, we only need a read lock (which prevents writing by
- * others).  However, if we don't have re-entrant functions, we can gain some
- * measure of thread-safety by using an exclusive lock during their execution.
- * That will protect against any other use of the functions that use the
- * mutexes, which all of core should be using. */
