I don't know if this is what's causing the problem, but there appear to be
cases where it can happen.
The DBMI driver, at least the way it is called by Vect_delete(), does not
inherit any file pointers, it gets only the names of the driver, database,
and table.
The only two file pointers in the map_info structure are those for the
hist and the coor file, and so far only these two files gave problems, but
not dbln, cidx, sidx, topo. Coincidence? Vect_close() does indeed close
the file pointers for hist and coor, I tested.

Can't reproduce any more, please ignore.
