Is this a rhetorical question?

If not, you could debug Emacs to look for the answer, although I expect it
comes down to the internals of Winsock.  But, if you can't find a good
reason there, then it must be a McAffee issue.  Actually, you might want
to start there anyway.  A review of their knowledge base might provide
some insights.  If you do find that this is some wierd Cygwin issue,
report it back to this list.
