On Windows flavors whose native shell is cmd.exe (NT, 2K, XP), but not on
those with command.com (9x, ME).

We're running Python 2.2.2; the C code for that is what it is.

Dig into the test line by line until understanding the cause of the problem.
It's not Zen that's lacking, it's someone to do that work; leaving a file
open isn't a "general principle" kind of problem, it's some path in the code
that left a file open.  In my experience, such paths are sometimes
exceedingly well hidden, as various subsystems of tests 8 levels deep open
and close files as side effects of setup and teardown methods, and two dozen
classes all have .close() methods and it's impossible to guess which one may
be intended by x.close() unless you know a lot about x.

Sorry, no idea.  When did you start seeing it happen?  I believe
checkReconnectReadOnly is a relatively new test, and also that adding the
ZEO tests to the general test mix is also a relatively new thing.
