Description
Continuously sorting a table by a column makes it perform slower and slower eventually resulting in OOM.
Comments
verified on build 42.

The issue as described in my first comment is apparently fixed. The symptoms remain, although to a much lesser degree and due to a different cause, for which a new issue will be filed once validated.

Please, provide a method on how to check this, or bug will be closed in two weeks. Build 42: (I tried to sort by columns in helloTableView many times and saw, how information in come columns disappear. I'll check this again and it will be a new bug, but i didn't see becoming more slow). If that enough to check performance bug, let me know, or close this bug.

Another scenario affected by this is rotating rows, essentially doing data.add(data.remove(0)) (PERF-172)

Thanks - I optimised some code in TableViewSkin such that VirtualFlow.cellCount was only updated if the oldValue != newValue. This inadvertently resulted in the sheet.children list never being cleared. I'll work on a patch that resolves this (by removing my initial optimisation the leak goes away).

This issue is very similar to RT-13965: sorting adds more and more cells to VirtualFlow.sheet which never gets cleared.
