no special environment needed.  (I was running bash2.)

>Description:

As root I exec'ed the following command from the shell and
brought down the system instantly:

exec /usr/sbin/pppd -detach connect "/usr/bin/chat -v -f \
	/etc/ppp/chat.dial" /dev/cuaa2

This is non-critical since I probably should have run it without
the -detach option and then just logged out normally; i.e. the
normal "workaround" is in fact the better way to do this.

>How-To-Repeat:

Create a chat script to dialup and start a pppd session and then
run the above code fragment.

>Fix:

I should have run it without the "-detach" option (but the system
should not have gone through a panic.
