types and objects are different things, though. to get an idea of how
much stuff Python loads using upstart, do "python -vv script.py" or add

import sys
print len(sys.modules), "modules"
print sys.modules.keys()

to the end of the script.

to get an idea of how many objects and types that are created at that
point, add

import gc
print len(gc.get_objects()), "objects"
print len(set(map(type, gc.get_objects()))), "types"

this gives me 35 modules (including the gc module), 3219 objects and 26
distinct types -- but the above will miss things, so the true numbers
are a bit higher.

(you might be able to use a debug build to get more detailed information)
