+// When running with ThreadSanitizer, we need to explicitly set some
+// options specific to our codebase to prevent errors during runtime.
+// To override these, set the TSAN_OPTIONS environment variable.
+//
+// Currently, these are:
+//
+//   abort_on_error=1 - Causes TSan to abort instead of using exit().
+//   halt_on_error=1 - Causes TSan to stop on the first race detected.
+//
+//   report_signal_unsafe=0 - Required to avoid TSan deadlocks when
+//   receiving external signals (e.g. SIGINT manually on console).
+//
+//   allocator_may_return_null=1 - Tell TSan to return NULL when an allocation
+//   fails instead of aborting the program. This allows us to handle failing
+//   allocations the same way we would handle them with a regular allocator and
+//   also uncovers potential bugs that might occur in these situations.
