[Swift-devel] progress stats lying

[Mihael Hategan]

The "Active" events are processed immediately, while for stageout events
to register to the ticker, it takes some karajan execution to happen in
possibly many threads and possibly involving scheduled tasks. This
causes the ticker to claim that more jobs are active than there actually
are.

A possible solution is to add another state ("Checking status" or
something), that is triggered in Execute by a task completed event.
