I've got this in one of my apps. Basically it forks, and exec's the SCGI
server again. It'd probably be better to get the file to exec from a
configuration variable than how I did it here.

def reset(request):
    import sys, os, os.path, time
    p = os.path
    moddir = p.dirname(sys.modules[__name__].__file__)
    # we're in __init__, so moddir is the dir containing capaweb/
    thisprog = p.abspath(p.join(moddir, 'capa_scgi.py'))

    root = '/'.join(request.environ['SCRIPT_NAME'].split('/')[:-1])
    request.redirect(root + '/')

    pid = os.fork()
    if pid == 0:
        raise SystemExit
    else:
        time.sleep(1)
        os.execl(thisprog, thisprog)
