This is most likely a random effect in the scheduling of the inititing
processes. Keep in mind, that those programs are using (n-1)/n of the
CPU, where n is the number of total processes (leaving out all other
system processes). The time a launching program needs to be run again
obviously increases with the number of processes. The small decrease
in between could be related to some penalisation of CPU bound processes.
