add some debugging stubs

The nasty bug that only shows up on certain machines
can be made very much worse by changing RedrawDelay to
something like 1 second.  Machines that are not subject
to the bug will simply exhibit a slow behavior;
machines subject to the bug will be turned unusable by
this change.
