So you're implying, that releasing the ucreds, that in this case
obviously prevent prisons from disappearing, won't work due to stuff
that "is releated to devfs and ttys"?

Or was that a kind request to have a look into potential ucred leaks in
tty and devfs code, as well? :)

What unwanted effects could an early release of ucred structures cause?

Maybe it was the wrong list to put that question on, after all, which
would be appropriate?
