i have a data cache which sits between a slow database and my server and
it's used to cache data retrieved from the database. in order for it to
work correctly (race-conditions) i need a fast deep-copying of
instances (the cache is used heavily).
i tried to use copy module but it's *very* slow, then i tried cPickle
to pickle and depickle instances which was faster, but still slow.
then i've come across cCopy which is 8x faster than copy, but
unfortunately it doesn't work with new style classes because type()'s
return is crappy for them. so the question is: does there exist a fast
copy module which works with new style classes?
