Comment(by drkirkby):
Whatever checks are being used to determine the cache size is not working
very well. First it reports the L1 cache size is 0, then it spends a
couple of minutes on a 3.33 GHz Xeon, to determine the cache size (I
thought it had hanged). It's also producing some NaN in the calculation of
the cache size - is that not a bug?
The CPU is an Intel Xeon W3580 and the operating system !OpenSolaris.
