of supporting architectures with different device names.
o Close /dev/tunX when destroying the bundle.
o Don't forget to close the parent end of the pipe in the child
process when exec'ing a program from a chat script.
o If we close our controlling terminal, ditch the current session
with it, allowing getty(8) (or whatever) to regain control.
o After transferring our controlling terminal descriptor to another
ppp instance, we now fork a new ppp to continue where we left off,
transferring ownership of all uucp locks and the /var/run/tunX.pid
file. Meanwhile the parent closes all file descriptors, defaults
all signals and does a pause() to wait for a HUP after the
transferred descriptor is finally closed.
We don't run /bin/cat any more (again!).
Suggested by: bde
TODO: It seems clocal devices need their pause()d session leader
to be given a manual HUP, as closing the last open descriptor
doesn't do the job.
