Or should I just leave the cracks -- they'll open up again if I fill
'em!

Squirt in some 3:1 PVA, don't rake out the cracks first. Use a squeezy
botle with a short length (2") of 15mm pipe lagging tied tightly around
the bottle top. Cut off the foam lagging at 90 degrees with a sharp
knife. Press the cut off end against the crack, squeeze until PVA has
gone in, stop when drips appear at each side of lagging where it presses
against the crack/ceiling. Repeat, following the crack along. Sponge off
x/s with a damp sponge. Wear a hat or something. Protect floor and
furnishings. Allow to dry, repeat optional, fill with polyfiller.
