[orca-list] When opening a folder with lot of files in it with Orca, it is very slow.

[Alex ARNAUD <alexarnaud hypra fr>]

Hello all,

A user has reported to me this issue with these folders with lot of data.

Environment:
- Debian sid
- Caja 1.20 / Nautilus 3.26.2
- Orca master

1) Create a folder and execute in it this script to create 1000 files in 
the directory
> #!/bin/bash
>
> for i in {1..1000}
> do
>         touch file$i.txt
> done
2) Launch Caja or Nautilus (here in icon mode)
3) Choose the directory with the 1000 files

Result: Orca will takes too much time to respond.
Expected result: Orca should be as reactive as the file manager is 
without it.

Best regards.
