-------------------------+--------------------------------------------------
 While testing the path bias code, I noticed a source of rounding error
 when we scaled our counts down while circuits are open. I corrected for
 this by counting the number of open circuits during scaling and
 subtracting that from our counts where appropriate, but a better fix might
 be to actually store separate pending counters that we don't transfer into
 the official, scaled counters until circuit closure.
