I haven’t finished the review of PR #348, but I wanted to pick up some changes that were made to master.
(the 5 second delay at sysout start, for example). Here's how I made this

mkdir new
cd new
git clone https://github.com/interlisp/medley
cd medley
git checkout Cleanup-character-IO-interfaces
git rebase master

which went into a loop where it would complain about conflicts, I’d do

git checkout Cleanup-character-IO-interfaces -- library/RDSYS library/RDSYS.LCOM library/exports.all loadups/whereis.hash loadups/*.dribble loadups/*.sysout loadups/full.database sources/ABASIC.LCOM sources/LLETHER.LCOM
git rebase --continue

and then exit the edit window that popped up

Then I did a loadup-all
Then I ran GATHER-INFO for the effect of loading records needed to
Recompile LLETHER and ABASIC

Then I did a new loadup-all
I then did a ‘start-release merge-ron-cleanup’ to make a medley and maiko release.

(I’m pretty sure it’s wrong to have combined medley + maiko releases. )
