It is, unfortunately this is only mentioned under "status" in
the ZCatalog interface. Well, I just got there by chance after 
several hours of digging around. I first thought perhaps some
DTML-Document was "bad-behaving". (not that I had an idea how
it might do that.)
With a (assumed) growing attractiveness of things like sql-based
UserFolders, perhaps a big warning sign either on the main page
of these products or ZCatalog (better IMO, since this is a default
product) would be in order, I guess. Or perhaps disabling 
subtransactions by default.
All in all this combination seems not uncommon.
