[New-bugs-announce] [issue17444] multiprocessing.cpu_count() should use hw.availcpu on Mac OS X

[John Szakmeister]

New submission from John Szakmeister:

While trying to test a fix for Nose, I discovered that multiprocessing is picking up the CPU count incorrectly.  It should be using hw.availcpu instead of hw.ncpu.  The latter is the number of cpus installed in the system, but the former is the number that are available for processing.  The processor pane let's you adjust the available CPUs, which is handy for testing and troubleshooting.
