I'd also like to write a scheduler that implements the narrowing event form the last scsh release, but without modifying s48 itself.

Is user code expected to use the upcall event, with some sort of token as the first argument to create their own events? I'll go forward with that solution if that's the case. I'm curious though; why are event-types are an enumeration, instead of just symbols or something similar?

I wanna start this while I have some momentum, so I'll just use upcall. Hopefully someone who knows will find the time to answer this eventually.
