	I have thought about two approaches:

	- a mechanism to send (rapidly) to the scheduler some info,
	  that it should get channels matching "smtp/*" into active
	  processing.  (That is, expire their timeouts)
	  That is (among other things) subject to system resources
	  at the scheduler -- if it can't start running those channels
	  due to lack of resources, what then ?

	- some people have asked for an ability to:
		- try to send with SMTP
		- if SMTP timeouts (no connection), send with UUCP
	  That can (perhaps) be solved with alternate-routes
	  mechanism, however it was never finished in the
	  original system, and there are just some hooks, but
	  small parts of it are still missing...  (Like a way
	  to handle interlocks of multiple channels processing
	  same message..  Consider the SMTP vs. UUCP above,
	  if BOTH systems send, you will get double delivery
	  every time..)
