What kinds of things would you want in the GNU OS?

? Certainly I don't think I've ever seen a problem with utmp.

There is no problem with utmp because noone tries to write in the
same place at the same time. It would seem that small writes within
a block *would* be atomic. The trick is to pick a small enuf number
on the right boundary and hope that this is true in all cases.

Directory writes are atomic because they are done by the kernel.

BTW, I agree with you that threads need not duplicate the stack.
It doesn't seem to make much sense what happens when a thread
returns/exits. However, I would rather see the kernel/library
push the address of thread_exit on the stack. Eliminates one argument.
