zen,

i doubt if you could use select() for the the different message queues, while you can do that for sockets. If you have multiple sockets and need to do event based handling depending on which socket you recv and what type of message you get, sockets are the ay to go. But the point to note is that its reliable, if you are pushing UDP packets internally within the system.

NAME

       dbus-cleanup-sockets - clean up leftover sockets in a directory

SYNOPSIS

       dbus-cleanup-sockets [DIRECTORY]

DESCRIPTION

       The dbus-cleanup-sockets command cleans up unused D-Bus connection sockets. See http://www.freedesktop.org/software/dbus/ for more informa-
       tion about the big picture.

       If given no arguments, dbus-cleanup-sockets cleans up sockets in the standard default socket directory for the per-user-login-session  mes-
       sage bus; this is usually /tmp.	Optionally, you can pass a different directory on the command line.

       On  Linux, this program is essentially useless, because D-Bus defaults to using "abstract sockets" that exist only in memory and don't have
       a corresponding file in /tmp.

       On most other flavors of UNIX, it's possible for the socket files to leak when programs using D-Bus  exit  abnormally  or  without  closing
       their  D-Bus connections. Thus, it might be interesting to run dbus-cleanup-sockets in a cron job to mop up any leaked sockets.	Or you can
       just ignore the leaked sockets, they aren't really hurting anything, other than cluttering the output of "ls /tmp"
