execl() will execute a new program in the current process, replacing the 
current process.  It obviously cannot return back to Python.  See 
http://www.python.org/doc/2.2/lib/os-process.html .

spawnl() will execute a new program in a new process, but it does not 
invoke a new *shell*.  It allows you to completely specify the 
environment, so this may also do what you want.  Unlike execl() you can 
return to Python after the subprocess is complete.
