[ZODB-Dev] profiling zLOG and inspect

So the best solution is to create a dummy module, as follows:

########################################
import os, sys

def LOG(*args):
    pass

if not os.environ.has_key("STUPID_LOG_FILE"):
    sys.modules["zLOG"] = sys.modules[__name__]
########################################

Now make sure this is imported in your main program before zLOG or
ZODB are imported.

The mysterious last line makes "import zLOG" return the dummy module
instead.
