I haven't had a chance to do any work to support the Solaris stuff, but
otherwise I'm just waiting on review.

Note that the patch doesn't do anything about long-running queries, it's
really about long-running connections/transactions. The server will only
notice the disconnected client once it tries to read/write something.

The whole point of the patch is that the system-wide defaults are
usually not useful. The current, unpatched, server turns on SO_KEEPALIVE
always, but the typical OS defaults set the timeout before probing to
about 2 hours.
