Summary: IO test failures

Initial Comment:

Really testing the tip of
the core-8-4-branch, where the
recent IO Finalization commits
have apparently broken a few
tests very seriously.  Here's the
first:

Message:

In my testing, Tcl 8.5.5+ and Tcl 8.6a4 
are not broken.

Only 8.4.19+ has crashes in the test suite.

Message:
FWIW, on my x86 CentOS4.6 it did crash reliably exactly as Don reported, so
the lates patch does improve things. But please test too ;-)

Message:
I can certainly revert ... Ah, I see a new patch was done. 

The interesting thing is that I ran the test suite here (linux) after
applying the patch and had no errors at all. For all branches. I am
guessing that you (Don) are either on a different platform, or copiled the
core with different settings than I did.

Which also means that right I am not a good place to check the new patch.
I will not know if my error-less state is because the new patch fixed
anything or because whatever else.

Don, can you please try Alexandre's new patch and report if that fixes the
issue for you ?

Message:
OK, see 2270477 for a better patch.
I have not yet got a chance to test it under Windows, but I'm rather
confident.
It might be an interesting alternative to pure reversion ;-)

Message:
Indeed it is far from trivial.
I reopened 2270477 to account for this fact.
Please Don or Andreas, do the revert on 8.[456].

Now to wash my shame :-P

Message:

FWIW, if this isn't very quick
and simple to resolve, I recommend
we simply revert, and let Tcl 8.4.20
live with whatever bug this patch
was meant to fix.
