With the thought of mod_python perhaps ignoring the PythonEnabledPdb

I wonder if simply examining sys.argv would work?
Can't be done this way as sys.argv doesn't even exist in mod_python.

Also need to sort out how -DONE_PROCESS and -X options are
different, as pdb support also works if -X option is used. This is
probably dangerous though to use as you still potentially get
child processes and thus fire off more than one request and they
will fight over standard input.
To determine if -DONE_PROCESS was used on the command line,
noting that -X is equivalent to -DONE_PROCESS and -DNO_DETATCH,
one can use in the Apache configuration file:
IfDefine ONE_PROCESS
PythonEnablePdb On
/IfDefine
As far as I can tell, the IfDefine directive uses the Apache C function:
ap_exists_config_define()
Ie., the defined symbol is the argument:
ap_exists_config_define(ONE_PROCESS)
Unless I am missing something, there is no equivalent to being able
to do IfDefine from within Python code executing inside of mod_python.
It sounds though that in this case with pdb that it might be a potentially
useful feature.
Thus, what do people think about a new function:
apache.exists_config_define(arg)
