Note that on Mac OS X 10.4 and later, you can #define FD_SETSIZE to
whatever value you want at compile time. In fact, you can allocate fd
sets dynamically so long as they are big enough to hold the largest file
descriptor you are using. See the comment just above the definition of
FD_SETSIZE in /usr/include/sys/select.h.
This is also true for other BSDs.
