Tom,

I think that James used this as input to the Timeline
program which he used to visualize how well work was
balanced among GC workers.  Relative values where
the only thing that mattered (not any units).

I noticed that the code for PrintGCTaskTimeStamps effectively prints out the raw ticks from os::elapsed_counter() without scaling them to a particular time base.  What's the intent of this output?  Is it assuming nanos?
