I'll look at it again when I get to the timeout code.

AIUI, what's supposed to happen is that select(2) returns 0 on a timeout.
By default, a TDS connection has no timeout, so a reading client waits
forever. But, we can allow the client to set a query timeout (dbsettime).
The select(2) in read.c::goodread() should honor that timeout.
