Then you can surely point out where my idea differs from, say, intel's or
motorola's idea of what registers are. Please do so, I

libeio actually makes no assumptions about the existance of an event loop,

I know, but that's not what I mean. I'm talking about reentrancy.
Right now the libeio API assumes that there is one event loop. The
want_poll callback assumes th

This is strictly less useful though, as you lose control over scheduling,
which might not be an issue for you though.

(Replying to libev mailing list so that Marc can see my reasons)
I see. My case is a lit
I'm writing a multithreaded evented server in which I have N threads
(N=number of CPU cores) and one libev event loop per thread. I want to
use libeio but it looks like libeio depends on global variables so
this isn't going to work. I'd like to request the ability to use
libeio with multiple event
