[boost] Boost.Python interpreter reinitialization problem

Hi,

We (the shop where I try to promote Boost) are using Boost 1.30.2 and 
currently the main focus is on interpreter embedding with Boost.Python.

I've hit a hard problem with this library.
For some reason, I would like to clean up the Python interpreter after 
performing some coputations with it and possibly reinitialize it later, 
if there is again a need to do some scripting.

In other words, my use of Python interpreter is tightly scoped and there 
are repetitive calls to Py_Initialize() and Py_Finalize() functions 
during the lifetime of the application.

The problem is that the initialization code that executes inside the 
BOOST_PYTHON_MODULE block (more specifically: the class_'s 
"definitions") throws when execituting for a second time:

"trying to register to_python_converter for a type which already has a 
registered to_python_converter"

This code is executed as a result of "from mymodule import *" Python 
command; the second execution is a result of running this command in the 
interpreter that was already finalized and RE-initialized.

Is there a way to re-initialize the module without re-registering the 
converters?

Hacking the Boost.Python library is a valid option, but I would need at 
least a suggestion where should I go.

Thank you very much for your time,
