|BigMath::log is slow for numbers greater than about 10, and can be made much faster by exploiting log identities. I submitted an RCR for this a year ago, and C Erler graciously optimized my reimplementation, but it looks like it died on the vine. Here's C Erler's message to ruby-core:

The maintainer, Shigeo Kobayashi, refused to apply this patch, since
he thinks this kind of optimization should be done in application
level.  I'm no good at mathematics, so that I had no way other than
trusting him.
