Two bugs in there. The FD issue seems to be Windows-Specific.

The swap.state one is wider. I've written it up as bug 2249
http://www.squid-cache.org/bugs/show_bug.cgi?id=2249

I've kicked off a clean build and test now on the 3.0 code to see if I
can reproduce it easily outside HEAD and since its more critical branch
at present.

It does not seem to be obliging. But don't have time to test properly
myself this week.
