Comment(by mikeperry):
Cool. A basic test calculating continuous entropy seems to show that the
slow guard runs can get entropy values as high as 6-7 bits, and hang out
around 4, where as the fast guards usually hang out around 2.. Looks
promising. However, I'm not sure if continuous entropy is what we want. We
may want to use the state file and compute actual entropy there.
I think this means I should write a tor patch to add an extra output item
to the BUILDTIMEOUT_SET info that calculates the discrete entropy of the
build times array.. Then we can look at our set of torperf runs and see if
anything pops out.
