Add all worker tasklets to a weakref set, and when the special tasklet wakes to an empty weakref set, block it on a channel. Then when creating a worker tasklet and adding it to the set, if the special tasklet is blocked on a channel, wake it up to continue being scheduled? Something like that. This is something you would do in "user space", in any case :-) Cheers, Richard. _______________________________________________ Stackless mailing list [email protected] http://www.stackless.com/mailman/listinfo/stackless
