  o Major bugfixes (OSX):
    - Fix coarse-time computation on Apple platforms (like Mac M1) where
      the Mach absolute time ticks do not correspond directly to
      nanoseconds.  Previously, we computed our shift value wrong, which
      led us to give incorrect timing results.
      Fixes bug 40684; bugfix on 0.3.3.1-alpha.
Fix a completely wrong calculation in mach monotime_init_internal() Bug 1: We were purporting to calculate milliseconds per tick, when we should have been computing ticks per millisecond. Bug 2: Instead of computing either one of those, we were _actually_ computing femtoseconds per tick. These two bugs covered for one another on x86 hardware, where 1 tick == 1 nanosecond. But on M1 OSX, 1 tick is about 41 nanoseconds, causing surprising results. Fixes bug 40684; bugfix on 0.3.3.1-alpha. 2022-10-13 19:40:10 +02:00			`o Major bugfixes (OSX):`
