As itojun pointed out, accept() used to just block if the socket it
thought it was going to give you turned out not to be there at the
last moment.  This was a killer for applications which expected
return from select() to be a reliable indicator of connections
waiting.

I think the proposed fix is the best one we can get right now.
Restructuring the TCP code to handle this case doesn't make a whole
lot of sense to me (or apparently to itojun or jlemon either).
