Comment (by chris_kohlhoff):

 Replying to [comment:3 anonymous]:
 > 1. Does disabling kqueue for a select based implementation have many if
 any drawbacks? (Is this documented somewhere?)

 If you use select then "the number of file descriptors in the process
 cannot be permitted to exceed FD_SETSIZE". This defaults to 1024 on Mac OS
 X.

 (From
 http://www.boost.org/doc/libs/1_46_1/doc/html/boost_asio/overview/implementation.html)

 > 2. Would you advise define'ing the BOOST_ASIO_DISABLE_KQUEUE in the
 compiler arguments or in the source code?

 You should prefer the compiler command line for these sorts of options. It
 helps ensure the option is consistent across your whole program.
