To delay or not to delay could be driven by how many items
are in the queue at that point in time.  If there are items queued
up then the user is scrolling faster than we can keep up, so
delaying a little would help in case another request comes in
that would take priority over the previous one because of the
FILO.  If we're able to generate previews as fast as the user
is scrolling and the queue is empty then we don't need to delay
at all probably.

Sounds like it could be a special --snapshot argument to mythtranscode.
