Comment:

 Marking to consider soonish.

 The patch as-is seems too problematic if it adds a timeout on the
 replication as a whole.

 Details of the socket timeout options (from {{{man 7 socket}}}):

 {{{
        SO_RCVTIMEO and SO_SNDTIMEO
               Specify the receiving or sending  timeouts  until  reporting
 an
               error.  The argument is a struct timeval.  If an input or
 output
               function blocks for this period of time, and data has been
 sent
               or  received,  the  return  value  of  that function will be
 the
               amount of data transferred; if no data has been transferred
 and
               the  timeout has been reached then -1 is returned with errno
 set
               to EAGAIN or EWOULDBLOCK just as if the socket was specified
 to
               be  nonblocking.   If  the  timeout is set to zero (the
 default)
               then the operation  will  never  timeout.   Timeouts  only
 have
               effect  for system calls that perform socket I/O (e.g.,
 read(2),
               recvmsg(2), send(2), sendmsg(2)); timeouts have  no  effect
 for
               select(2), poll(2), epoll_wait(2), and so on.
 }}}

 Though I've read a few (perhaps dated) warnings that they aren't
 implemented everywhere.
