Rename AsioConditionVariable to AsioEvent
...
The current implementation is rather similar to Python's threading.Event, than to a CV.

CpuBoundWork#CpuBoundWork(): don't spin on atomic int to acquire slot
...
This is inefficient and involves unfair scheduling. The latter implies
possible bad surprises regarding waiting durations on busy nodes. Instead,
use AsioConditionVariable#Wait() if there are no free slots. It's notified
by others' CpuBoundWork#~CpuBoundWork() once finished.
