[Users] Is there a stable OpenVZ kernel, and which should be fit for production

[Stephen Balukoff]

Oh!  And for what it's worth, we're seeing this on both the latest
stable RHEL6 kernel, as well as the latest testing RHEL6 kernel
available in the repositories for download.  (That is, 042stab39.11
and 042stab044.1 respectively).
