From Gerri:

this patch sets the timer resolution in such a way that it is 10ms for
timeouts <= 200s and 5 / 100000 of timeout for longer timeouts.
There is no magic behind this fraction: it just gives 10ms at 200s and
it covers with some margin the drift we observe on the CAF for 1h delays
(117 ms vs 36 * 5 = 180ms).

With this change things on the CAF work fine.
