Is ib_sort_* the only temporary files? I have eng*.tmp and LB*.tmp
too... Do these belong to firebird?
Hum... Shouldn't ib_sort be renamed to fb_sort???? hehehehe

Right again, I was doing some testing with some queries involving
joining views that take too long to return data, so that I decided to
restart the service manually... After some trying I could delete most
of the files.
