Monitoring stage thrashing cpu core

[jimboid]

This is totally unnecessary behaviour, this will be due to the introduction of the new timing code, where as the old code used to do lots of checks that would prevent full utilisation of the core, now the new code allows the checks to be done only at specific time intervals. The effect of this is that the core running longbow is thrashed, whilst the only thing happening is spinning the counter and waiting to do checks.

Perhaps a solution to this is to work out some sleep intervals that will take account of both the status checking time interval and the file staging time interval.
