Yes, host.capacity can be changed on the fly and kojid will handle it
just fine.

If kojid shuts down cleanly it will free all the tasks it is currently
working on, to make them available for another builder to process.  On
startup is also frees any tasks it owns before starting to process new
tasks.  In general a kojid restart may result in running tasks being
started over, but nothing worse than that.
