This is a very good point.  Another thing to consider is that static 
tests may not be as valuable as one thinks since the default thread 
size may abe a system configurable option so the problem can be solved 
(or aggravated) by changing a system setting.  Do to this, it may be 
useful for operation to be influenced by a run-time setting rather 
than compiled in.

Requesting the desired stack size (at run-time) is the obvious first 
step, but of course the system is not required to support the 
requested stack size.
