worker: support more return types in posix worker

This allows us to return things that aren't tuple(int, str) from worker
functions. I wanted to use marshal instead of pickle, but it seems to read from
the pipe in non-blocking mode, which means it stops before it sees the results.

The windows worker already supports arbitrary return values without
serialization, because it uses threads instead of subprocesses.
