process management

Processes hang around, as you might expect. First of all, pman is the Erlang process manager. Start with

1> pman:start().

Hide system processes to make it a bit clearer for now. If we run the simple message passing example from here, then we can see that a play:receiver() process is left hanging around after everything stops.

2> play:start().
in receiver <0.46.0>
rx: hey <0.47.0>
<0.47.0>
in receiver <0.46.0>

To kill the process, highlight it with a click and choose Trace/Kill. pman has a default 5s refresh, so it’ll not disappear immediately…
