> Running ThreadSanitizer (http://clang.llvm.org/docs/ThreadSanitizer.html) over "make check" yields ~262 warnings/errors (data races, use-after-free, and similar).
> Notes on running tsan:
> * CXXFLAGS="-fsanitize=thread" LDFLAGS="-fsanitize=thread"
> * This creates an additional thread, which breaks a few (fragile) tests; will be reported separately
> * I ran into some problems using tsan w/ GCC 4.9; using clang 3.6 worked fine.
