I agree - I've been playing with insanely fast IO servers (where insanely fast
means 30k FDs pushing out a few hundred mbits of traffic) and I've hit syscall
throughput limits.

It'd be nice to attach actual buffers to kqueue messages which the OS could
fill out for you - that way you could do network IO in a pair of syscalls -
but I've been a little busy. :p
