I guess my vacation successfully purged my memory.  I was thinking the
switcher was only a complie-time option, but just realized that it can
be disabled at runtime (via /sys/kernel/bL_switcher/active.)

With the runtime enable/disable feature of the switcher, I don't have
any more (reasonable) objections to it being enabled by default.
