//
// 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.
