Make it a pointy stick and I can improve on that.
I've been thinking that we could do with a CONFIG_RC_KERNEL or something
which gets turned on up until -rc4 or so, then gets turned off. So we can
make the devel kernels more debugging-friendly.
The main problem would be remembering to turn the dang thing off and on at
the right times.
