I have never done this in python; but, using the normal system calls in C
the process is basically:
	
	1. fork() a  new process
	2. the child process changes its user id with setreuid() and
		possibly its group id with setregid()
	3. then the child exec()s new process which replaces itself

All of the necessary functions should be under the os module on POSIX
operating systems.
