It has just occurred to me - duh - that the process ID of a back-shell
command is a perfectly good unique ID for it, and more useful than
any connection id/message id thingy.  Doesn't need extra arguments
to the shell commands either, except a pid: line to abandon.
And msgid: can still be removed in a future version.
Here is a patch.
