I've forwarded your emails to the dbus development list to hopefully start
a discussion as to whether there is a bug in dbus or dbus-cxx' use of
dbus.

In the meantime I've commited what I hope will fix the problem. It's
difficult for me to test since my systems don't seem to experience the
same bug.

In short, the fix (hopefully only temporary until we figure out which
library the bug is in) simply initiates processing in the dispatch thread
if any read or write watch activity occurred.

That should allow the dispatch thread and watch thread to operate at full
capacity without any dependent locking and still make sure that any
silently queued messages are still dealt with.

The fixed version is currently in subversion:
http://sourceforge.net/projects/dbus-cxx/develop

Let me know if this fixes the problem and I'll push out a general release.

Thanks Patrick for tracking this one down,
