openvswitch has some tricks to overcome the socket path length
limitation using symlink.  (or procfs where available)
iirc these were introduced for debian builds which use deep CWD.

http://git.openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=blob;f=lib/socket-
util.c;h=aa0c7196da9926de38b7388b8e28ead12e12913e;hb=HEAD

look at shorten_name_via_symlink and shorten_name_via_proc.
