Hi Gerard,

the test don't time out; they run a fixed amount of time. Sorry, "Timeout" was a bad phrasing here.

Moving them out of tier1 (or alternatively just getting rid of them) would be fine but as a separate RFE. The former would require either splitting gtests into several units, some tier1 worthy, some not; or to reimplement them as jtreg tests (as they had been before). Both is significantly more effort than I want to put into right now.

Thanks, Thomas
