Currently it was possible that PopAll returns 1010 items, then
makes one RPC call with 1000 items, then RPC call 10 items. Meanwhile,

This change ensures that we pull items from the queue early and
try to make rpc batches as large as possible.

This adds a piece deletion handler that has debounce for failed dialing
and batching multiple jobs into a single request.
