I'm not sure if that's going to work. We have tests covering a lot of 
stuff already; if we change some of it, then some of the tests will 
fail. If we don't store disp for visible items, so we can pass the new 
test, then the test at line 1360 will fail.

There's also the test at line 1383. Which is same as line 1360, except 
that it also has the CODEONLY flag (its "disp" was still retrieved 
earlier, though). In that case, the disp is not used.

Both of them have the VISIBLE flag -- and yet only the former one 
accesses its disp. I don't know how to solve this situation without 
checking the flags.
