It's hard to say for sure, but my guess is that it's Cygwin's gethostname
function which calls winsock's implementation of same.  The winsock
gethostname implementation will apparently access DNS for the name of the
current machine - go figure.  FYI, gethostname is called at least when you
log in, to set the prompt and all...
