Have you considered ReadyExec?
It's a C client and a Python library for running more-or-less arbitrary
Python programs as daemons, using Unix-domain sockets. It doesn't
automatically start the daemon, but you might be able to add
that. Meanwhile, the C client is extremely small and should be quite
fast. The "protocol" is also simple and fast: stdin/stdout/stderr are
handed to the daemon directly via OS-level file descriptor transfers, and
only the command line arguments and environment are pumped over the socket,
