Description:
Please make skip-thread-priority into a compile time option, and enable this for all OS X binaries. Currently the default action of using thread priorities on OS X degrades performance and Apple has no plans to change the thread scheduler in the near future.

How to repeat:
See above.

Suggested fix:

The patch was pushed into 5.1.15 on Jan 11 already :-(

Noted in 5.0.34, 5.1.15 changelogs.

The --skip-thread-priority option now is enabled by default for
binary Mac OS X distributions. Use of thread priorities degrades
performance on Mac OS X.
