Something I never quite understood: differentiate between BEAM process and operating system process. The OS has launched one (in theory) BEAM Erlang VM runtime process with N threads; are we saying “process” here to try to emulate the OS process model internally within the BEAM OS process, when really we’re talking about threads? Or a mix of threads and other processes? I’m imagining the latter even cross network, but am I at least on the right track here?
