There's modern systems like OSX where poll() doesn't work on a variety of things like terminals.

dbus-cleanup-sockets
dbus-cleanup-sockets(1) User Commands dbus-cleanup-sockets(1)
NAME
dbus-cleanup-sockets - clean up leftover sockets in a directory
SYNOPSIS
dbus-cleanup-sockets [--help] [--version] [directory]
DESCRIPTION
The dbus-cleanup-sockets command cleans up unused D-Bus connection sockets.
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 is 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 clean up any leaked sockets. Or you
can just ignore the leaked sockets, they are not really hurting anything, other than cluttering the /tmp directory.
See http://www.freedesktop.org/software/dbus/ for more information.
OPTIONS
The following options are supported:
--help

directory Clean up sockets in the specified directory rather than the default socket directory.

0 Application exited successfully
>0 Application exited with failure

/usr/bin/dbus-cleanup-sockets Executable for dbus-cleanup-sockets
