Hi,
I'm wandering whether it's worth the efford to make the
in-kernel number of pty's more dynamic. This would mean
that the pty table woud be elrarged as necessary. The 
space allocated for ptys would never be freed, so this
would work similar way as e.g. vnode cache. The maximum
number of ptys would be controlled via sysctl.

Note this is not mentioned to be full pty clone support,
there would still be those /dev/ttyp* files and
the way pty is open from userland would not change.
The only change would be that the code would allocate
extra pty structures in kernel if necessary.
