-          The maximum number of Unix98 PTYs that can be used at any one time.
-          The default is 256, and should be enough for desktop systems. Server
-          machines which support incoming telnet/rlogin/ssh connections and/or
-          serve several X terminals may want to increase this: every incoming
-          connection and every xterm uses up one PTY.
-
-          When not in use, each additional set of 256 PTYs occupy
-          approximately 8 KB of kernel memory on 32-bit architectures.
