this doesn't work with the current SVN version of RRDtool: Because
CREATE is issued via the daemon as well, absolute paths are not allowed
for network sockets. Use a UNIX domain socket if you need absolute

This is odd: It should read:
  PENDING remote_peer_data/rp4.rrd

Works fine here. src/rrd_fetch.c hasn't been touched since the daemon
code was introduced and the daemon code is basically the same as the
other commands, so I doubt the problem is there. You could strace the
command to check if there's an error condition that's not reported, but
I believe it's more likely a file name was mixed up.
