Isn't libevent[1] the same sort of thing? I believe it is the C-based<br>
asynchronous programming library underlying memcached[2], which in turn<br>
is used by several high-profile web applications -- their website lists<br>
Wikipedia, WordPress.com, Flickr, Twitter, Typepad, Youtube, LiveJournal,<br>
Digg, Craigslist, and a handful of others I didn't recognize.<br>
<br>
I dusted off the ocaml bindings for libevent[3] at home last year and<br>
found them pretty usable for the small experiments I did (implementing a<br>
monadic interface for CML-style concurrent programming). Their website[1]<br>
claims "Libevent should compile on Linux, *BSD, Mac OS X, Solaris,<br>
Windows, and more."<br>
