Log Message:
Add lots of comments explaining what is happening in here.

Also enhance some of the DEBUG mode trace output (nothing visible
in a normal shell build).

A couple of very minor code changes that no-one should ever notice
(eg: one less wait() call in the case that there is nothing pending).
