arbitrary command through pseudo tty (pty).

3. What you can do
This extension module defines a module named PTY, which contains
following module fungtions:
getpty(command)
spawn(command)
This function reserves a pty, executes command over the pty
and returns an array. The return value is an array with three
elements. The first element in the array is for reading and the
second for writing. The third element is the process ID of the
child process. If this function is called with an iterator block,
the array is passed to the block as block parameters, and the
function itself returns nil.
When the child process is suspended or finished, an exception is
raised. If this function is called with an iterator block,
exception is raised only within the block. Child process
monitor is terminated on block exit.
protect_signal
reset_signal
These functions are obsolete in this version of pty.
