pychecker probably tries to delete some ObjC-code-containing extension 
modules from sys.modules, which causes Bad Things To Happen if their 
ref count goes to 0 and python tries to unload the bundle.  pydoc can 
quite easily cause this problem.  Try doing the following at the top of 
your module:

# horrible_hack = (
import sys
sys.modules['*' + __name__] = sys.modules[__name__]
del sys
# )

This will cause your module never to be released/unloaded because there 
will be the sys.modules['*'+__name__] reference.  It shouldn't break 
anything, because '*' is not a valid character in a python module name.
