Well first do step zero, and find out if doing the connection
setup teardown is really the main cost :-).

As you're doing a specific set of operations on a specific share,
seems to me it might just be easier to create a new python
wrapper call that creates a frame, gets the service and then
does the required calls from parameters passed into it.

Why call out to python at all, just do it all in C ?
