No, I meant `check-timers', so the default behavior is modified, but you can recover the previous behavior by passing an extra argument. >> In the long run, we should try and clean up sit-for, but you may not >> have the courage to dig into this right now. > I'm arguing I don't need to dig into sit-for's complexity to maintain > its current behavior.

That's theory: there is no thread-yield right now, nor any timer-check. > Also, what do you think are the merits of putting in the > specpdl-walking check discussed earlier, enabled with > --enable-checking? I like the idea, tho I'd have to see the code first to know whether it should depend on --enable-checking or something else. Stefan
