How about this...use two scripts.  One for myth that takes an arg, and
then calls the second in the background while returning control to
myth, and the second to do the real work.

ie:
Listing of changeexternchan.sh
------------------
#!/bin/bash

reallychangeexternchan.sh $1 &
------------------

where reallychangeexternchan.sh is your script from above.

I actually do something similar, except my "really change external
channel" is a daemon that is always running, listening on a named
pipe, so myth's channel changer simply writes the channel number to
the named pipe and exits, letting the daemon handle the rest.
