For what's it's worth I didn't notice any slow down running a NAMD
test with tracing disabled and ~400000 tlbie's in 34s. Turning tracing
on could have slowed things down ever so slightly, but I didn't notice
as it may have just been in the noise of the benchmark I was running
(I wasn't specifically looking at timing, hence the vagueness of the
remarks).

Otherwise the patch worked and would be useful - I have already had to
setup tlbie counting/tracing several times in the last 12 months.
