-// Do not use ManagedStatic, or that may allocate memory while attempting to
-// report an OOM.
 //
 // This usage of std::mutex has to be conditionalized behind ifdefs because
 // of this script:
 //   compiler-rt/lib/sanitizer_common/symbolizer/scripts/build_symbolizer.sh
 // That script attempts to statically link the LLVM symbolizer library with the
 // STL and hide all of its symbols with 'opt -internalize'. To reduce size, it
 // cuts out the threading portions of the hermetic copy of libc++ that it
 // builds. We can remove these ifdefs if that script goes away.
