I think it helps make the runtime testing more consistent but we are seeing 
a number of "qemu didn't start in 120s" messages instead. That is probably
more desirable than random runtime failures in qemu.

We have still seen one valgrind ptest failure with the tmpfs patch too so it
doesn't remove all of them.

It also won't fix the bitbake server starting timeout problem.

I'm leaning to merging it.

I did note that in the 120s qemu timeout, we did get a list of other
processes that were running:

https://autobuilder.yoctoproject.org/typhoon/#/builders/80/builds/1973

and it shows webkit being built. Would be interesting to correlate against
other failures, see what the pattern of running tasks is.

Cheers,
