Fractional durations (e.g. 0.5s) for the sleep command are useful and
not terribly uncommon in practice, especially in scripts associated
with test cases (e.g. mdadm, lttng-tools). Enable FEATURE_FLOAT_SLEEP
by default in order to avoid having to patch every instance of a
script using a fractional sleep.
