pseudo terminals in 7.0 - pts implementation

Hi,

7.0-BETA3 still has issues regarding the pts implementation .
problems found:
1. - GNU screen: starting a screen, opening a few windows and quiting screen leaves the allocated pseudo terminal in use. 100 screen user, using each one opening 10 windows will deplete the default of 1000 pseudo terminals leaving the system unusable. 
2. - 'ls /dev/ptmx' creates an additional entry in /dev/pty/. when the number of entries equals kern.pts.max the system became unusable.

this feature is very important for an access server.

Please help me find/solve the problem.

Regards,
Gepu
