I am sorry to miss your instruction of using macro instead of direct bit
and Thanks for your work!

I think we can hold the pshared stuff until we have cross process
You can commit other man pages.
2. Should there be more technical review for ad@'s priority inversion work?
Yes, we should. We need more persons with deep understanding of NetBSD
(like you and Martin) to review
the patch before we commit because it is not a small feature.

This patch actually makes use of MINSIGSTKSZ, which is a fixed value in
NetBSD and is arch dependent
in FreeBSD (the accurate name is __MINSIGSTKSZ). So, we may go to the
FreeBSD's way to make
the macro arch dependent if there is no netbsd specific reason to keep it
as a const.
So to conclude, the action items for me is to
1. add unit tests for ad's work to make sure it works well.
2. may add some changes according to your comments on PTHREAD_STACK_MIN.
