Undo "Revert "Small changes to threading to send thread names to unmanaged threads. Needs Mono 3.6+ to see thread names in utilities like top -H . Some formatting of the thread name to fin in the 16 byte limit on Linux. Please test on Windows to see if the work has any adverse effects.""

Fix for break in next commit

This reverts commit 376fab1402.
