We need to do some development whichever way we go. The epmd code does
not work with s4 at all at the moment.

If you are worried about the event loops then run it in standard
mode. It then runs in its own process.

We have a nice task abstraction in Samba4, and I don't like the idea
of losing that abstraction. It has served us very well.

To get the most use out of the epmapper work that Andreas has done I
think the code would need to be refactored as a library, then called
from both RPC servers.
