Well, my server process maintains a list of other processes associated with
unique keys in a dictionary, and I have found out that if the server process
itself crashes, I am able to recover process pids and keys directly from the
supervisor (I have a secondary dedicated supervisor for those processes);
for now I am not trapping exists, but it may become useful later...
I may also save that data in some persistent locus, if needed.
