*nod*  I imagine the graphs will be kind of big, but at least it's a 
starting point for figuring out what your system is doing.  There are at 
least two python APIs to dot.

Nope.  I did a KDE-only install (following the instructions on the 
Fedora Myth(ology) site for MythTV), and I checked after the install to 
see which gnome packages it had installed.  I didn't see any gnome-* 
packages.  A "yum update" and a huge-ass download later, and I had both 
x86_64 and i386 versions installed.

Are both architectures actually needed?  Or is this some failsafe mode? 
Can I disable it?

Thanks.
