[Tilesathome] Why sleep when you could render?

[Dermot McNally]

A quick thought: When the upload queue is full, the client sleeps
until it can upload again.
Is there any reason it couldn't simply start processing the next tile?
Clearly this will mean that the next upload attempt will contain more
tiles, but I suppose the assumption is that a full queue should be
temporary, so this should have the net result of processing the job
queue more quickly.
