Well either way, if a couple of Nmap scans can crash a system there's
obviously something wrong with it.

Yes, I fail to see why nmap should be at fault. It's like "fuzz"
testing (http://home.pacbell.net/s-max/scott/bulletproof- 
penguin.html):

You throw crap at some (program|system) and if it crashes, you found a
bug (in the program/system, not in the crap :) )

I would second this as the CLOSE_WAIT state according to everything I  
have seen,
and I just verified it with TCP/IP Illustrated, is the network stack  
waiting for the server application
to respond to the fin sent by the client.
