~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2009/04/08 - sjoerd: runtime/pathfinder.mx,1.450.2.9
Normalize thread stack space usage: THREAD_STACK_SIZE is the size allocated,
not 2*THREAD_STACK_SIZE or 4*THREAD_STACK_SIZE.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2009/04/09 - sjoerd: runtime/pathfinder.mx,1.450.2.10
We need more slack space on top of when the highwater mark is last
checked. I made the amount dependent on the architecture. We'll need
to see if that is ok.
