The only extension I currently know of using the new calls is
'Thread'.

I see no big complications with that. ... Ok, the changes I did are in

	2000-05-03-20-24.diff.gz 

of my cvs snapshots. There are some other changes in as well (joinable
threads), but it should be possible to trim it down to contain just
the changes to the IO-system. We'll have to see how many chunks are
still applicable. File attached.

Excerpt of ChangeLog of the lastest 8.3.2-io-rewrite.

* tests/all.tcl: corrected additional sets by Kupries for testing.

I'm chagrined. My apologies for that oversight.

I truly wish there was some way to set such things separately during
development without having to modify the distributed files
themselves. => Some idea for Jennifer Hom and her planned changes to
tcltest.
