-// Sometimes, we can try to get a stack trace from within a stack
-// trace, because libunwind can call mmap (maybe indirectly via an
-// internal mmap based memory allocator), and that mmap gets trapped
-// and causes a stack-trace request.  If were to try to honor that
-// recursive request, we'd end up with infinite recursion or deadlock.
-// Luckily, it's safe to ignore those subsequent traces.  In such
-// cases, we return 0 to indicate the situation.
-// We can use the GCC __thread syntax here since libunwind is not supported on
-// Windows.
