No, this is problem in CVS code. I just checked, GDS_Impl.disconnect
(db) is called only when database is created (ok), in
isc_attach_database if error occurs (ok), and in GDS_Impl.connect(db)
if connection was not accepted. I think we must close it when
isc_detach_database is called.

I'm going to incorporate this fix into the CVS code.
