I think it is a bug...
It clearly is nondeterministic. Sometimes the load average sticks at
.5, sometimes at 1, for you it apparently sticks at .34
It can suddenly ramp up and ramp down, sometimes to 0 and sometimes to
integer values. From the above values it kind of looks like it sticks
at "n" or "1/n" where n is an integer.

I think this has to be fixed, the load average is not just "some toy"
but it is (or at least was) a measure for system load that can be used
by some processes to make decisions about starting background jobs, etc.
