Process status objects are stored in master process, and since they
generally do not consume much memory, i do not see any reason for
exponential growth in process size. Also, there is no garbage
collection apart from default Ruby one.
However, if you are worrried about growth of memory because of that in
long run, you may try to pass memcache option in configuration file,
so as status objects are stored in memcache.
