I lack the higher-level picture.  Can you describe in a few words how
will this work in a running Make?  I don't mean the details of how
files are locked and unlocked (I understand that part), I mean the
larger picture, like how it will look to the user, how several
programs running in parallel will write their output and in what order
it will appear eventually on the screen.

Thanks, and sorry for not being able to grasp all that from those URLS
and the code.
