embedding python in a multi-threaded C++ application

[lukas]

I am debuggin a C++ multi-threaded application that need to
talk to sendmail. Sometimes the process that runs the application
freezes up for 2 minutes while the python code is running. 
Any ideas?  I am running on Solaris 2.7 and using Python 2.1.


What are the issues in having a C++ thread calling python?
Is there any documentation about:

- embedding python in C++ app?
- multithreading issues in python when embedded in C++?


thank you for any help.

Lukas.
