Huh? These sockets aren't handled in a single process, are they?
Nowadays, this number of sockets does not pose any problem for most
systems, especially if you don't do I/O multiplexing. Of course, if
you've got 10,000 connections which are active in parallel, most users
won't be content with 1/10,000th of your database performance. 8-/ (I
don't see why idle connections should be a problem from a socket
management POV, though.)
