There is a saying in german, "the problem was between the chair and
keyboard". Your analysis was almost entirely correct, except that
I was not running pppd in diagnostic mode. Keyboard interrupts that
I was typing on the same tty where I'd started pppd (using
adsl-start) were somehow being propagated to pppd and killing it.
THERE IS *NO* PROBLEM WITH ntpd. sorry about the confusion.
