I don't think this is true any longer. I believe that the Extended Time
Manager gets its greater resoution (250 microsec) by letting the
hardware count down, rather than doing its own counting in tmCount.

I use the Time Manager -- even in the brackground -- in the DTS sample
code FracApp 2.0. I've never noticed any problems.
