[Building Sakai] Losing pages from sites

[Matthew Buckett]

We've had an issue locally where a large number of sites were lost
when a user used the page order helper to unhide some tools.

On a local copy of our 2.8.x instance I can reproduce the loss of a
page by using a jmeter test to repeatedly hide/unhide a page.

Has anyone else seen this or know if it's fixed (I couldn't see
anything in Jira about it).
