Bleh. Whatever the system clocks ticks per second are on that system, it's 
apparently not managing to hold 10_000_000 hnsecs accurately. I suppose that the 
asserts on 1504 and 1506 will have to be made to use <= instead of ==, at least 
for the moment. I expect that that would fix them. Still, this variance in 
precision and the fact that Windows doesn't appear to have anything approaching 
a round or consistent (across systems anyway) number of ticks per second is 
definitely annoying when it comes to crafting appropriate tests.
