Arrgh. As long as we have that "SMP makes locking harder" myth floating
around we _will_ get problems. Kernel UP programming is not different
from SMP one. It is multithreaded. And amount of genuine SMP bugs is
very small compared to ones that had been there on UP since way back.
And yes, programming threads is the same thing. No arguments here.
