From talking with Ryan, I don't think we need to track intermittent failures from beta simulations. Other than asking Jeff to have a look, there's not a lot I can do here since it's not something where we can find a regression range. Aryx, what do you think?

Yes, no need to track intermittent failures unless they are very frequent.

:jgilbert there seem to be rather many such failures (on the integration trees), gl jobs with timeout and crash after with this signature: [@ libsystem_kernel.dylib + 0xsth]: bug 1469272, bug 1468373, bug 1468479, bug 1469202, bug 1469111 etc. Do we keep filing new bugs for these failures or should we make a general one for all of them? Thank you.

General bug. Hopefully we can get more of a handle on these with the splitting of mochitest-gl in bug 1471112.
