> The ManagedProcess kill() method relies on a scan of running processes that have a command line with -D[<processname>] in the command line, refusing to do the OS kill if > 1 such process is found.
> This is troublesome if you have > 1 HC on the machine, as they are likely to use the same process names (e.g. "Server:server-one"). So the 'kill' doesn't happen, and destroy() gets used instead. Destroy doesn't seem as strong, as it seems to not prevent shutdown hook execution, leaving open the possibility of hangs.
> Perhaps the PC could generate a random int or even a short and include that as a param on the command line as well, then use that as part of the discrimination check.
