I guess some daemon could poll the GPS and hold off starting ntpd until the
ephemeris is downloaded.

The almanac may take 12 to 24 mins to download, but the almanac is just
for predicting future GPS sat locations.
I'm sure there a few small cases where my simplification is not right,
but I've not seen PPS shift from the alm

older GPS, the current leap second offset is known. But now ntpd is
set in its ways, and will take a while to slew to the correct time.

No process "owns" the SHM. Think of it just like a file.
