Queue more input buffers and process more output if possible.

Queue more input buffers and process more output if possible.

We only attempt to queue a single input even though we might be
able to queue more than one. There may also be more input to
queue after dequeing an output.

BUG=601066
TEST=multiple inputs queued sometimes.
