Hmmm ... So this is something that would be needed for communication
to external but it wouldn't if we did just in inproc, right? Not sure
I like it then. It makes the internal communication between LogMgr and
LogWriter quite complex for a case that'll be pretty rarely used
Here's an alternative suggestion: why don't we leave the
LogMgr-to-LogWriter channel simple and just do inproc communication
there. Then, in addition, we can create a LogForwarder class derived
from LogWriter that in turn uses 0mq to talk to the outside the work.
This forwarder can be as complex as needed, and just like any other
writer it would run in its own thread.
Does that make sense?
