According to Michael Tokarev, the guest is swapped out and needs to handle a timer interrupt. It gets swapped in by the host, but this takes some time. The next timer fires BEFORE the previous timer, so the guest thinks that the interrupt is too slow and things go downhill from there.
This does not resolve the problem, but it allows the guest to handle it gracefully.
