<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">OK, so it seems gproc:monitor(Key, follow) works, however if the name is already registered the message {gproc, registered, Ref, Key} is not sent. I would have expected the message to be sent since {gproc, unreg, Ref, Key} is sent when the name is not registered. Is this a bug?<br>
