I've taken a stab at implementing the DTrace "sched" provider, for most
of the probes listed here which made sense:

Please note that this was my first foray into the scheduling code, as
well an early effort at implementing a dtrace provider;

Yep. Reducing blocksize to 8192 makes it barf on 8192+ byte files.
