[RFC] Another Para-Virtualization page recycler. Empty Guest OS free pages every few seconds

PPR (Per Page Recycler) is a para virtualization driver currently available for KVM hosts and Linux/Windows guests. With PPR, every page freed to Guest OS can be recycled in seconds by hypervisor. Therefore, VMs can dynamical allocate/free pages from hypervisor according to application’s
