In fact I have a patch for OS/X which should be in asio 0.3.3. However
I believe the functions it uses are not guaranteed to be thread-safe
until 10.4, so you would only be able to use asio in a single-threaded
program for earlier OS/X releases.

Basically the approach I have been taking has been to make asio
portable first (via select) and then to optimise for each platform. For
example, it theoretically supports implementations that use /dev/poll
on Solaris and kqueues on on *bsd (including OS/X AFAIK).
