The Windows kernel may still work, but that doesn't mean that everything
Postgres depends on still works. I'm wondering about (a) the TCP stack
(and that includes 3rd party firewalls and such, not only the core
Windows code); (b) timing or threading stuff inside the application
that's using libpq, which the only thing we know about so far is that
it's *not* JDBC/Hibernate.
