137ccd9dd9 Minor changes to wording and formatting in the README 
The wording in some places is not grammatically correct. This change
also provides minor adjustments to the Markdown formatting which provide
modest improvements to readability.

bb9876db33 Fix thread races and infinite looping on systems with many cpus 
On systems with more than 64 cpus, blas_quickdivide will sometimes return zero which creates bogus workloads when used for the stride calculation. This then leads to threads spinning incessantly waiting for a status change that never happens, as seen in #1497.
This patch also fixes several data races that were found by helgrind and/or tsan while debugging the issue.

f81815e48a Fix CMake cross-compiling 
Without specifying thread count, NUM_THREADS would not be defined and CMake would fail.
This is because core count cannot be determined when cross-compiling.
