[luatex] parallel computing

Hi all,

I think this has been discussed a few times: An a multi-core computer,
*TeX can only use one core as the typesetting process is linear. Now, I
had an idea and wanted to ask what is stupid about it (elsewise it would
have been implemented already, I guess):
While the breaking of paragraphs is linear, there is a second process
that starts only after paragraph breaking has been done, which is page
building. Now I could imagine a *TeX that lets one core do the paragraph
breaking and another one do pagebuilding. Depending on which one of
those is faster, the paragraph breaker has to be stopped at a
(specified) number of lines it is in advance of the page builder. If the
page builder is faster, everything is fine from start on.

Thankful for any comments,
