Subject: [PATCH] fork_init: Update max_threads comment

The comment explaining what value max_threads is set to is outdated.
The maximum memory consumption ratio for thread structures was 1/2
until February 2002, then it was briefly changed to 1/16 before being
set to 1/8 which we still use today. The comment was never updated
to reflect that change, it's about time.
