EVFILT_USER?

[coypu%sdf.org@localhost]

Hi folks,

Do we have anything that resembles EVFILT_USER?
Apparently, it makes it possible for userland to send events around.

This came up in a programming language port.
https://github.com/ziglang/zig/blob/master/std/event/loop.zig

I assume (based on a superficial reading) that I would like to have a
thread sleep on something, then have another thread wake it up, in
userland.

the linux equivalent code seems to be using futex_wait/wake.

thanks.
