That was true when just about *anything* went wrong in that
environment, though -- I don't think you can blame while True
in particular for it.

(I remember my earliest Mac programming experiences, back
when the Mac was too small to run its own development
environment, and everything had to be cross-compiled.
Debugging consisted of counting the number of times
SysBeep got called before the bomb icon appeared...)
