Do not use this bone-headed license.

The Fedora people have identified a problem with it.

TL; DR: the CC0 license explicitly says that it's granting only use and redistribution in a copyright sense, and not granting any patent or trademark rights.

This is different from a truly free license like BSD or MIT which grant unlimited redistribution and use.

I wonder if HdrHistogram[1] could have done the job. Didn't find any references to that one in the post.

Because of the name, it took my brain a few seconds to realize this is not related to mercurial.
