[erlang-questions] enif_send backpressure

It's my understanding that if a normal Erlang process does Pid ! Msg, and
Pid has a particularly full message queue, then the sending process is
penalised (gives up the remainder of its timeslice, e.g.).

Is there any way to implement something similar for enif_send from a NIF?

I'm calling it from a background thread in my NIF, and it'd be nice if it
(e.g.) returned the size of the recipient's message queue, so that I could
implement backpressure in my NIF.

Any ideas?
