[PATCH] D29588: Use rw locks for sanitizer thread registry

[Kostya Serebryany via Phabricator via llvm-commits]

kcc added a comment.

This is a very invasive change with a potential to break lots of things in subtle ways. 
It has more chances to get reviewed and accepted if you

  a) test it on something very big (and tell us what you did) and
  b) add a test that fails now and passes with this change. 

Also, please make sure to have LGTM from dvyukov before committing.
