This is one of these things that is very surprising to me: I always 
thought and assumed and apparently never double-checked, that templates 
are only reloaded when zope is running in "devmode on".

This is indeed not the case: whenever `__debug__` is True, the template 
is reloaded.

Do people actually run their serves with `python -O` (which would make 
`__debug__` False, but also would make assert statements to be skipped)?
