ret what you are asking about and changing it abit.
Don't you think that Maturity can be defined ALSO, as the
number of known bugs and their priority / serverity against a
architecture dependent or independent item?
Would this suffice and wouldn't it be easier to ma

memory increases in a system this probably could
be decreased somewhat to maybe 1.25x.
IF the above is good then the issue is how to optimize the heck
out of the check.

2x of LOW_MEMORY equiv of the freelists and to re-populate them.
Then, HOPEFULLY the 2nd time calling get_page_from_freelist() would
then be obsolete.
When I come up with it, I will suggest it to the group.

missing is the RT for .task_new.
No class specific initialization needs to be done for RT tasks.

What a brilliant idea in a world where buying
the schedular / dispatcher to do what
you think should be done, I would suggest submitting
a prototype to Ingo, et al and see what the response
