Isn't this better after:

As Peter pointed out, most of these are fuzzy sync tests and the runtime
is callibrated in order to get reasonable chance of reproducing the
results. But indeed the runtime does not scale with the speed of the
machine and we are not setting the pair exec_loops in the tests that run
for so long, so I suppose that callibrating the number of loops for
these tests that does not make the bug less reproducible would make
things better.
