It would be interesting to see whether the same happens with IB/6 and
IB/7. As you know, the special GC thread was introduced after
IB/5.6. Maybe it should be possible to configure Fb to _not_ use the
feature.
I've also seen (the unsettling) CPU intensive activity when closing an app
(but only for a few minutes (I think) with a small (less than 1GB) database).
