Previously I thought that one interrupt per batchbuffer should be enough. Now tedious benchmarking showed this to be wrong. Therefore track whether any commands have been isssued with a future seqno (like pipelined fencing changes or flushes). If this is the case emit a request before issueing the batchbuffer.
