I don't think we should ignore them for a couple reasons:
1. may be really hard in future to go back and figure it out, much
harder than it is today.
2. may indicate an effective issue that we are ignoring and maybe it's
just not that bad on other platform, but exists.
Btw, Edmorley was working on trying to make a regrange using inbound
builds and standalone talos (we have the builds, just not the data).
