We need to be careful here. We have the ability to totally overload any 
reasonable build system, and going through a full build and test for 
what are sometimes small changes may be impractical (having 100+ 
developers waiting for the build queue is also a _bad_ thing.)

As Joe Darcy often points out, we need to be careful that we are not so 
afraid of doing anything bad that we prevent anything good from happening.

Note, I am /not/ saying we don't need a good build and test system.  We 
do.  We just need to be careful how we mandate its use.
