[bf1942] Server Utilization

I can't say why some servers are showing this behaviour, but it seems
to depend on your kernel configuration. Last summer I received help from
a community member and we tested many configurations and found the
culprit to be SMP kernels causing a massive CPU overhead.

The same machine running a non-SMP kernel would not have the high-idle

The carrier problem should be fixed in 1.6 since we have reverted the
carrier collision meshes back to the 1.31 versions which didn't have
the problem.
