[mod_python] Reimporting again and again

Greetings.

This is my configuration -

FreeBSD 4.9
Python 2.2.3 (--without-threads)
Apache 2.0.49
ModPython 3.1.3
I also did the 'setenv LD_PRELOAD /usr/lib/libc_r.so"

There is an index.py which has three functions.
Every time a call is made to one of these three
functions, there is an entry (a "notice") in the
"error_log" that this module is being (Re)imported.

Why so ? Can someone please explain what's going on ?
Or am I missing some flags/directives that I should
have set ?

Any ideas ??? Please help,

Thanks,
Krishna.
