sem command creates unnecessary processes: processes_available_by_system_limit is called by compute_number_of_processes but sem doesn't run jobs in parallel, hence there is no need to check that $self->user_requested_processes($opt::jobs) processes can be created.

A proposed patch is attached.

The test suite requires some executables which I wasn't able to find/install:

How to install them ?
