Redis CPU load is so high when using Coverband::ResqueWorker with a lot of resque jobs and RedisHashStore

our production servers process a lot of resque jobs.

Coverband::ResqueWorker#perform reports when the job finished, so CPU utilization of our Redis store for collection coverage data goes too high.

yeah sadly the forking model adds a lot of overhead for collecting and reporting coverage as it is forked per job... You can see we have some specific integrations support for resque, but it is not the most efficient...
