Without knowing much about how it works, it's easy for me to believe
that it is convoluted.  Watching system calls via strace for a different
embedded application, I could see it searching around for a python 
executable, and that was a bit shocking.  That experience was what led
me to search for and then use the Py_SetProgramName() function.

BTW, how exactly does one specify an environment variable like PYTHONHOME 
within an apache config script?
