One thing to note about kudu and dragonfly is that they are running under 
vmware.  This, combined with cygwin's reputation, makes me suspect that 
the connection is that they are both struggling under load.  Although 
canary (NetBSD 1.6 x86) is setup in the same fashion and has shown no such 
failures.

I'm also in the process of moving, so I put this machine in a box last 
night and it won't be up and running for a week or two.  I do have very 
similar copies of the OS image running on other machines if you'd like me 
to test something specific.
