The source of an "External Method" can be read arbitrarily often --
and each time, you extend "sys.path"...
The "imp" module allows you to import modules without the need
to modify "path".

Python does not recognize at runtime when a module source has
It provides however a builtin "reload" which you can use
to explicitely reload a module.
Be warned the "reload" is dangerous. Funny effects can happen.
As someone else suggested, restarting Zope is the safest way
(although not the fasted one).
