It is turned on at configure time as a static extension so it impacts
all threads that are created.

This is a possibility.  I would really like to see a "debug/profile" 
alternate build version of RTEMS that turns on all the heap checking,
stack checking, mutex lock order checking, etc. It would be considerably
slower and more code space but worth it from a consistency check.

If there were a set of global debug settings, then these checks could
be in the build and turned on and off at run-time.
