       Arch::RunLimit provides an easy way to enforce a limit on the number of concurrently running processes.

       The following methods are available:

       new, exceeded.

       new%opts
           Create a new Arch::RunLimit object with the specified options:

           file (mandatory)
               The file used to keep track of the number of processes.

           limit
               The maximum number of concurrently running processes. Defaults to 5.

           timeout
               The  timeout  after  which a process is assumed to be terminated in seconds. Defaults to 1800 (30
               minutes).

       exceeded
           Return 1 if the number of concurrently running processes has been exceeded, 0 otherwise.
