 Phase 7 (TBD) - Sharing of variables between threads (ideally without limitation, but that might not be realistic)

+Mutex TODO:
-- create a branch and try to use CK atomics. - seems done, just keep an eye on this
-
-- multiple mutators, and threading functions/types.  probably want this on a new branch, when ready
-  part of this is implementing the beginnings of srfi-18, to create multiple threads, sync them, etc
-  next steps:
   - add mutex type, and associated functions from SRFI-18
     when allocating a mutex, probably should do it on thread since by definition these are
     shared among multiple threads
   - may be able to free mutex using mutex_destroy from within gc_sweep.
     unfortunately it requires type checking each object before free, which is not ideal
