I've reviewed the code briefly and afaiu it wraps the data to HTTP on 
the *socket* level.

However, note that data sent to the socket are not necessarily aligned 
with 0MQ messages.

Thus, it can happen that a HTTP message will contain tail part of some 
message, one complete message and beginning on another message.

As a side note: The patch seems to mix several issues. AFAICS aside of 
HTTP thing, there's some logging functionality, some PGM related changes
