Right, when I was profiling stuff my baseline was just a pair of 
processes that did read() and write() on "char buf[128]" or something, 
blocking in each direction. i.e. attempting to profile purely the cost 
of the read and write.

iirc ORBit was not dramatically slower than that raw socket case, so I 
think dbus:orbit and dbus:sockets is about the same measure. But, it was 
many years ago.
