I'd like to hear why my code wouldn't work.  Keep in mind that nothing
keeps track of connection objects except for $sys, which starts off
with a clean slate.

If you put it in the wrong place, yes.  The code should be placed near
the beginning of $sys.startup().

This is *not* the right way to do it.  It will leave one connection
object, but there is no guarantee that it is the particular one that
the system object has as the receiver on the port.  You got lucky.
