Yes, that's the puzzling bit; although I don't have nearly the same
number of history lines in .bash_history, but the difference still is at
least an order of magnitude.

I think so.  Since I switched very early to the LDAP integration code
and have been running on snapshots most of the time since, I can't
really say when exactly this was introduced.

Understood.  The timing seems about right, I first noticed this
beginning of December.
