yes, we got most of the problems (crashes / corrupted libraries)
during / after VM migration, so it seems to be the best trigger
so far

yup, it's still migrating, it's been another 3 days since upgrade to 7.3-rc7,
another 107 cycles (of ~160 VMs, some of them pretty large), still no problem.
it starts to look rock solid to me.

it doesn't seem to affect users in any way, so I'll just keep it running
and report if I get some issue
