@fowlduck @bascule @charliesome Doing scheduler checkpoints in func preludes is pretty good. I'd bet even Erlang does that.
@evanphx @fowlduck @charliesome yeah, Erlang preempts on "reductions". It also stalls on "NIFs" that call out to native code, which sucks

@bascule@evanphx@fowlduck@charliesome I'm pretty sure that it's impossible to call C efficiently if you have a userland scheduler. -
@pcwalton@bascule@fowlduck@charliesome The calls outside the view of goroutine (ie cgo) are pretty slow, yes. -
@evanphx@bascule@fowlduck@charliesome Deal-breaker for many apps. -
@pcwalton@bascule@fowlduck@charliesome Sure, definite trade off.
