Speaking of the FD_* macros and such, I'm trying to visualize how to re-write some code that I have that relies on the socket_fd_* functions. If you get the chance, could you look over this simplified version of what I'm doing and point me towards the proper direction to get it working with the new API. I want to have this stuff ready when PHP 4.2 or 4.3 come out, and seeing as you're the one closest to the sockets extension, I thought you could give me some pointers as to how it would work with the abscence of the sockets_fd_* functions. (I'm a little confused what to do without the FD_* stuff. This could make for a good example in the documentation, anyways, if it works as hoped.)
