The first one wouldn't work for sure.  Second one works if python
is in /usr/bin, third one works if python is in some directory in
PATH and env is in /usr/bin.  Assuming your own shell is bash,
try "type python" and "type env" to see where those programs are.

spawnv returns a process ID, if you use os.P_NOWAIT.  It returns
the process exit status if you use os.P_WAIT.  If you look at the
code, in os.py, you will see that this second variation is essentially
implemented by applying waitpid() to the first.
