The getloadavg() function returns the number of processes in the system
run queue averaged over various periods of time. Up to nelem samples are
retrieved and assigned to successive elements of loadavg[]. The system
imposes a maximum of 3 samples, representing averages over the last 1, 5,
and 15 minutes, respectively.

ber of samples actually retrieved is returned.
