Not that I know of. If you look at section 6.1 of the library
reference, you'll see that things like os.fork() is only
available in unix etc.

In unix and friends you would change "start %s" to "%s &". I
don't know about MacOS. I suppose MacOSX works just as unix,
but I don't suppose that works with previous versions.

I reasonable approximation might be (untested):

import os
def runDetached(cmd):
     try:
         fmt =3D {'nt': 'start %s',
                'posix': '%s &'}[os.name]
     except KeyError:
         fmt =3D "%s"
     os.system(fmt % cmd)
