With the document from fdo#75622, this saves 3775 calls and leaves only 13.
e586fe45 removed avoiding the call
to LayoutTable(), which made loading slow. I checked that the doc from that
bugreport still works, so if very original code was correct in avoiding
the call sometimes, this should be ok too.
