shared lib from python code?

[Gabriel Rossetti]

Hello everyone,

I would like to know if it is possible to turn python code into a shared
lib? I have several processes that use the same base code, and it seems
like every process loads the "shared" code into memory. I would like it
to be loaded once and shared, like a .so in linux or a .dll in windows
and have the interpreters use the dared copy. Is there a way to do this?

Thank you,
Gabriel

I guess it's not completely inconceivable--Emacs used something called
unexec back in the day, that transmogrified part of its data segment
into the text segment and dumped it out as a runnable binary--but it
doesn't seem worth it nowadays, given how small your .pyc's are likely
to be relative to the size of memory. If you're concerned about the
import overhead, maybe you can structure your program as a persistent
process instead of re-running it all the time.
