[racket-dev] I/O scheduler change --- epoll(), kqueue(), etc.

I already relayed this good news (and the good news about byte I/O 
recently) to one of my clients, who is a large user of Racket for Web apps.

I suspect this improvement will mean noticeably better responsiveness 
for them under load, and perhaps fewer servers.
