class EventQ::WorkerStatus
Class used to represent the main worker status and the collection of forked worker processes. The main worker process will not have access to a forks collection of processes and threads. This is due to forks getting a copy of the process memory space and there is no such thing as shared resources between child processes and the parent process. Without implementing a need using inter process communication with IO::Pipe, only the PID is of any use for the parent process. To summarize, if using forks, the parent process will only have a collection of PIDS and not any threads associated with those PIDS.
