That's impossible.  Objects are just memory, and memory cannot be shared
between processes.

You can certainly create a new logger instance in your spawned process
and have it write to the same file.  As long as the logging module
flushes after each write, that should work.

Another alternative is to use popen instead of spawn, and have your
spawned process write its messages to stdout.  You could then echo them
on to the logfile in your original process.  That has its own buffering
problems.
