rpc or other processes will cause one or two persistent processes to start up during the test, but the number shoould not increase after that. Altered the test to check for massive increase in processes over a larger number of faults rather than an equality of process_count over a relatively small number of faults.

%% @doc The purpose of thie test is to ensure the realtime helpers on both
|
|
%% the source and sink sides properly exit when a connection is flakey; ie
|

%% then there are errors and not out-right closes of the connection.
