With two threads and a check interval og 100, only 61 of 100000 check intervals failed to produce a thread-switch in the interpreter. I'd call that rather fair.

This number lacks the elapsed time. 61 switches in one second is probably enough, the same amount of switches in 10 or 20 seconds is too small (at least for threads needing good responsivity, e.g. I/O threads).

Also, "fair" has to take into account the average latency and its relative stability, which is why I wrote ccbench.
