/* 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. */
