Is the ESX multi vCPU /page sharing bug still present in ESXi 5?

Hi

I've recently upgraded to ESXi 5 from ESX4.0

With ESX4.0, we used to have to disable page sharing for multi CPU VMs due to a bug that causes these VMs to take over 5 minutes to reboot if page sharing is enabled, see the following VMWare KB for details about this:

Does anyone know of any VMware documentation that shows that this has been address in ESXi 5? I've searched but can't find anything.

Thanks

Joe
