Yes, I was just looking at that and working up what I believe will be a
fix.  This is exactly the kind of test I was anticipating getting run
unintentionally on Windows, sorry about that, but I don't have a Windows
test environment currently.

I've pushed what I believe will fix this, which is essentially "don't
try to run this test on this platform."  Tested it locally (under Linux)
and it didn't blow up, so hopefully this doesn't make things worse, in
any case.

If there's more that's needed to fix jacana, I'll see about dealing with
it first thing in the morning.

Thanks!

Stephen
