Thanks for confirming this.

Well, the workaround is completely inert for all configurations, so in
some sense it's fixed already.

That said, to try to fix it for real, we would need to determine what
subsystem is causing the problem.  It could be the fault of IIS, or it
could be the fault of the PCGI code.  To determine which, a setup could
be established that uses PCGI under Apache; alternately another
mechanism besides PCGI under IIS could be used (a couple folks have
posted howtos about using IIS as a proxy to Zope instead of using
PCGI).  If we find that only happens when using IIS, then the problem is
likely Microsoft's.  If we find that it only happens when using PCGI,
then the problem is likely Zope's.

I don't have much interest in running this particular bug down (I don't
run Zope on Windows nor do I ever run PCGI), but maybe someone will find
it interesting enough to take it up.
