>+Running D-Bus clients with Valgrind
>+====
>+
>+When running programs using libdbus in Valgrind, some special care needs to be
>+taken so as to avoid incorrect detection of leaks in libdbus. To avoid these
>+false positives, do the following:
>+
>+* Grab a copy of the D-Bus source code
>+
>+* Run configure with the --enable-developer and --with-valgrind options
>+
>+* Run make
>+
>+* Either make sure your code calls dbus_shutdown() (at least while running in
>+  Valgrind) or set DBUS_MESSAGE_CACHE=0 in your environment
>+
>+* Run Valgrind on your program with the /path/to/dbus/source/dbus/.libs in your
>+  LD_LIBRARY_PATH
>+
>+Your Valgrind log should now be free of any (spurious) libdbus-related leaks.
>+
>+For the curious, the DBUS_MESSAGE_CACHE=0 is required because by
>+default, libdbus uses a recyclable pool of message structs. These help
>+performance a bit.
