I think you might be better off using system(), or popen() (or popen2()) if
you need to pipe stuff into (and out of) the process. I found the following
works:

>>> import os
>>> os.system("/usr/bin/vim")

I'm not sure why execve() doesn't work, but I presume it might be something
to do with the command taking over the process which calls execve(), whereas
I presume system() etc. spawn a separate process. Maybe the real experts can
help here :-)
