Tino Reichardt e7b64159f8 ZTS: Optimize Kernel Same-page Merging (KSM)
Kernel same-page Merging (KSM) allows KVM guests to share identical
memory pages. These shared pages are usually common libraries or other
identical, high-use data.

The current configuration was a bit to lazy - so KSM didn't work very
well. With the new configuration I could run 3 Linux VMs in parralel.

FreeBSD can't benefit from it. But FreeBSD is not so memory hungry in
general, so there is no need for it ;)
