But doesnt the fact remain that counting the recursion depth is dangerous?
Im thinking of embedded environments, where a) the stack size of the hosting
.exe can't be known and b) the stack used by the app before Python is even
called can't be determined. Add to this callbacks in GUI and COM type
applications, and we seem to be applying more band-aids.
The idea of counting space used seems better, but still assumes a known
