I have accidently discovered a workaround, which may provide a hint as to the failure mode: For performance, I had been mounting my home directory with 'noatime' specified as an option. On a whim, I deleted that and let it take the default (seems to be relatime). Lo and behold, the problem is gone! I will revert this as soon as I get an opportunity and see what is mounted (or not, as the case may be) when the symptoms appear.
