[Python-Dev] Best Python API for exposing posix_spawn

[Pablo Galindo Salgado]

I think I really like Antoine's suggestion so I'm going to finish
implementing it that way. I think this keeps the API simple, does not bring
in the os module new dependencies, keeps the C implementation clean and is
consistent with the rest of the posix module. I will post an update when is
ready.

Thank you everyone for sharing your view and advice!
