------------------------------------------+--------------------------
 The Math class now exposes high-precision versions of several mathematical
 functions. If these are OS-specific, they may be fingerprintable.

 OS-level fingerprinting probably is not a terribly high priority. The only
 situation where this is high priority is if different OS versions and
 library versions end up producing different results for these functions.
