What is happening is that while tracing, edebug is waiting for an input
event with "(sit-for 1)". When you type the "S", sit-for pushes it onto
`unread-command-events' and returns. Unfortunately, before calling the
recursive edit into the edebug command loop, `unread-command-events' gets
bound to nil, thus edebug doesn't see the "S". The motivation here is
probably to separate the "outside" event queue from edebug's event queue.
Here is a fix (which Eli will probably call a workaround ;-). In trace
mode, the top event (if any) is pulled off the "outside"
`unread-command-events' and pushed onto edebug's binding of it.
