[zeromq-dev] ZMQ_MCAST_LOOP with PGM

[Pierre Ynard]

Hello,

I took notice of https://zeromq.jira.com/browse/LIBZMQ-104
and of the removal of this option, but I have
trouble understanding the issue. Even after reading
http://lists.zeromq.org/pipermail/zeromq-dev/2010-June/004133.html
I don't get it.

Are we talking sender or receiver side of the transport here? What is
specific to loopback with this? Isn't it impossible to have several
sockets listening on the same unicast address anyway?

Anyway, is it safe to enable this option if I don't mind about
reliability?
