@fowlduck @bascule @charliesome Doing scheduler checkpoints in func preludes is pretty good. I'd bet even Erlang does that.
@bascule @evanphx @fowlduck @charliesome I'm pretty sure that it's impossible to call C efficiently if you have a userland scheduler.

@pcwalton@bascule@evanphx@fowlduck@charliesome what does calling C functions have to do with scheduling ? -
@phenlix@pcwalton@bascule@fowlduck@charliesome C functions are unknown code. Might to a blocking syscall or hot loop. A bad black box.
