Or even simpler:  Halt processing of incoming packets from
interfaces until done with the log.

I'd rather not lose good information that might be coming in.  I can
imagine cases where critical positions come in at just the wrong
time during a SAR mission or public service event, and you wouldn't
want to be there with your face turning read when they asked you for
the most recent position.  Of course that would happen anyway if the
log replay was still going, and going, and going...

I would call it VCR controls, or tape-player controls, but pretty
soon nobody will know what those are.  Shall we call them DVD
controls just to be safe?

You're not going to want a reverse button and alternate endings too,
are you?  ;-)

I like your idea for a playback window.  It would also allow us to
have a "read at maximum rate" button for those times when we want to
reconstruct our display in a hurry.
