For OpenVZ the reason is not CFQ fair scheduling only
(which is not that fair actually in our tests done inhouse),
but more in the fact that anticipatory scheduler has some bad issues
with sync. on some real life workloads (e.g. with SMTP agents)
anticipatory fails to work with reasonable performance.
