http://docs.python.org/2/library/functions.html#reload says:

It is legal though generally not very useful to reload built-in or dynamically loaded modules, except for sys, __main__ and __builtin__.

It is unclear what the "except for ..." part is referring to.  Is it not legal to reload those modules?  Or is it not very useful to reload them?

The python3 docs say:

"It is legal though generally not very useful to reload built-in or dynamically loaded modules (this is not true for e.g. sys, __main__, builtins and other key modules where reloading is frowned upon)."

So, it is the former...sort of.  You don't get an error when you reload them, so implying that it is not "legal" is an odd phrasing.  Probably that sentence should be clarified in both the python2 and python3 docs.
