Is that mod_python or is that the prefork MPM?

I've never had to care.  :)  A quick poke through mod_python.c shows
mod_py tries to be resilient:

...
   resultobject = PyObject_CallMethod(idata->obcallback,
"HandlerDispatch", "O",
                                      request_obj);

   /* release the lock and destroy tstate*/
   release_interpreter();

   if (! resultobject) {
       ap_log_rerror(APLOG_MARK, APLOG_NOERRNO|APLOG_ERR, 0, req,
                     "python_handler: Dispatch() returned nothing.");
       return HTTP_INTERNAL_SERVER_ERROR;
   }
...

I fear I've wandered off-topic, but I guess my philosophy in writing
server software is that no bug in a handling a single request should
affect the handling in other requests.  That and $1 would get me a cup
of coffee, since I have yet to write any HTTP server software.  ;-)
