Now I got a DMM(*) on loan and I re-ran the checks: voltage only, not 
the resistance checks because I didn't want to remove the PIC: the 
reading is now about 8.5mV AC ripple, well within the limit.

Apparently, the room where the assembly takes place does have stray RF 
around: short-circuiting the probes gives a reading of 5mV, holding them 
close together reads 300mV and spreading them 1 meter apart peaks at 530mV.

Thanks again,
Andrea.

(*) The DMM itself is a "FUKE DT890B+" (yes, "FUKE") and either it's a 
"fluke" Fluke (meaning cheap copy of Fluke) or it's a priceless typo 
(like some rare pink stamps 8-)
