Mutex on _CONFIGURE_MUTEX in automap.prepare()
Fixed a race condition which could occur if automap
:meth:`.AutomapBase.prepare` were used within a multi-threaded context
against other threads which may call :func:`.configure_mappers` as a
result of use of other mappers. The unfinished mapping work of automap
is particularly sensitive to being pulled in by a
:func:`.configure_mappers` step leading to errors.
