If indeed Bug 1147148 - M2Crypto usage in vdsm leaks memory
does not manifest itself with m2crypto-0.21.1 and is limited to el6,
it's great news.

I've move the bug to RHEL6's m2crypto. I hope it can be solved there,
properly.

Until this takes place, we can place Daniel's m2crypto build somewhere
and suggest people to use it (preferably, we'd take a koji scratch build).

We should not drop it into the default ovirt repo just yet, as no
package is error free, so we should better check this new m2crypto
first.
