generic/095 doesn't take more than 4 seconds on any of my test setups,
but is exercises code that handles buffered write iterations interrupted
by concurrent direct I/O that no other test in the quick group does.

Yeah, it generally takes ~5 seconds. But there's a "LOAD_FACTOR", so
before we add it into quick group, I'd like to ask
do you think if it's worth increasing the default LOAD_FACTOR a bit to
give it more stress, or move it to quick group directly?

I'm fine with it as-is.  Despite being in the stress group, this test
actually provides code coverage not provided by other quick tests even in
the most basic version.

On what kind of storage hardware?  If it's that fast even on spinning
rust then I guess you could double the iodepth*/numjobs computations.

(What happens if numjobs exceeds the 9 defined in the fio config file?)

I'd move it to the quick group.

OK, Christoph likes that too, let's move it to quick.
