I'm reading through plperl and plpython implementations and I don't

Comments for plperl say that there are two interpreters (trusted and
untrusted) for each user session, and they are stored in a hash.
Plpython version looks quite different, there is no such global hash
with interpreters, there is just a pointer to an interpreter and one
global function _PG_init, which runs once (but per session, user, or
I'm just wondering how a plpython implementation should look like. We
need another interpreter, but PG_init function is run once, should it
then create two interpreters on init, or should we let this function
do nothing and create a proper interpreter in the first call of
plpython(u) function for current session?
python does not any any sort of reliable sandbox, so there is no
plpython, only plpythonu - hence only one interpreter per backend is needed.
