So it does.  On Windows the error msg is a bit different:

select.error: (10038, 'An operation was attempted on something that is
not a socket')

Looks like these come out of two related tests:

    testNOK (ZEO.tests.testAuth.PlainTextAuth)
    testNOK (ZEO.tests.testAuth.DigestAuth)

Curiously, the same tests pass on Zope 2.8 trunk under 2.4, and in
Zope3 under 2.4.

Unfortunately, I have no idea what those tests do.  Possibly relevant
is that 2.4's asyncore is less tolerant of leaving garbage in its
socket_map (like closed sockets).

One other thing to note:  a lot of deprecation warnings about
importing whrandom.  That module has been officially deprecated for
years (although the warning is new in 2.4) -- it's high time to stop
importing it.
