Subject: [PATCH] tests/nap.h: increase delay multiplier to avoid problems in
 VMs like OBS

The gnulib change http://git.sv.gnu.org/cgit/gnulib.git/commit/?id=5191133e
(available upstreams with >= 8.22, applied to openSUSE's coreutils
package with "coreutils-gnulib-tests-fix-nap-race.patch", decreased the
probability of lost races to about a third, however such problems could
still be observed in virtual machines like OBS.
Increasing the factor from 1.125 to 3 seems to close the race window.

* tests/nap.h (nap): Change the multiplier for the delay from 1.125
to 3.
