htop scans /proc to determine how many running tasks exist. Since that 

operation is not possible to be conducted in an atomic fashion, task
scheduling effects can lead to a count greater than the number of actual
processors; this is more easily noticed on machines with several CPUs
and under heavy workload.
This patch simply adds an upper bound on cpuCount to guarantee
consistent reports of the number of running tasks at any given time.
