Ah yes, I hadn't considered that. Is this a Python limitation?
Py_Initialize() seems to initialise a global Python object which
obviously makes it awkward to share. Other languages allow you to
create multiple instances (eg. Lua has lua_newstate() which returns a
new Lua state) which would facilitate running multiple interpreters
without the new process overhead. A brief search implies that mod_perl
doesn't have the same problem as mod_python (but has other problems).
It would be a shame if Python is almost alone in having this issue.
