inspect.findsource does not call linecache.checkcache
thus always returns orignal source of an object
regardless of wether it has changed.

Actually, I'm not sure if this is really a bug, seems to
make sense that inspect shouldn't return the new source of
the object unless the object has changed.

Not to mention there's intermediate steps where an object's
source could change several times, and be reloaded at one of
those intermediate steps... seems like there's no way for
findsource itself to return the correct source for an object
if it's reloaded. Maybe this should be documented...

Note that if you tack on

execfile(somefile)
print inspect.findsource(foo)

at the end of the example, so that the object does change, 
you still see the old source.

Issue 1218234 has a patch.

Setting it as a superseder, then.
