Would people be interested if I added such a feature? Limit the
highest allocatable pty to 90% when operating within a jail? e.g.
if you have 256 ptys both jail and normal tend to allocate ptys
from the bottom up, but the jail would not be allowed to allocate
past pty #227. This way if a jail eats all the ptys the sysadmin
can still ssh in.
