simplifying things like delay pools

Benno's SSL patchset does an interesting thing - it overloads the socket
read() and write() into a per-FD function pointer pair, so SSL connections
don't need evil if (ssl) { } else { } wrapped around them.

I was thinking that this also might be good for delay pools - instead of
having all the delay pool ifdefs floating around read()s you could just
overload read() and then stick the delay pool magic in there.

What do people think ?
