Description of problem:

'nc' doesn't honor the '-w <val>' argument for timing out connection failures

Version-Release number of selected component (if applicable):

1.82-fc4.1, 1.84-3.2 (FC5 source recompiled onto FC4)

How reproducible:

Every time.

Steps to Reproduce:

Create a DROP firewall on a test machine for a port.

1. nc -w 2 <test machine> <dropped port>
 
Actual results:

Command hangs until TCP connect timeout

Expected results:

Previous versions of nc (in particular 1.10), and documentation and help state 
that 'Timeout for connects and final net reads'.  It is not exiting or timing 
out after the defined '-w' period of seconds if the connection attempt hangs 
(as when a machine is under load, or trying to connect to a dropped port).
