MPS issue job001622

TitleClient can't multithread on OS X.
Assigned userDavid Jones
DescriptionClient can't multithread on OS X.

Multithreaded clients will crash MPS. Well, unless they implement
their own locking.

Clients that wish to register the stacks of more than one thread
will also need an MPS with a working thread module. See
AnalysisNeed a lock implementation for OS X.

Probably the POSIXy one in lockfr.c is POSIXy enough for OS X.

Testing by drj on 2007-02-20 indicates that when lockfr.c is
modified to remove its #if tests for being compiled on FreeBSD
it works just fine on OS X without any other modifcations.

2007-03-12 DRJ

Implemented lockix.c on Darwin as a more-or-less straight copy of
lockfr.c (which will be removed as part of job001636).
