As I recall, "touching" the TB simply means reading it and computing
elapsed ticks since the last read. I don't remember anything changing
the value in the timebase registers (which isn't possible outside
of the kernel).
I regularly use the TB for user application event timing, and
haven't seen anything abnormal (other than the code I was testing :-).
