  Log Message:
  -----------
  fix infinite loop in (cast()super).toString

- the compiler doesn't recognize this as super call
  and will use dynamic dispatch leading to an infinite loop

  spinlock for GC

- less overhead than pthread_mutex
- uses test and test-and-set algorithm with configurable backoff

  Log Message:
  -----------
  avoid any GC deadlocks

- always use runLocked which now unlocks on error
- check for recursive GC entrance during finalization
  inFinalizer can be thread local b/c we're finalizing in the
  same thread that currently holds the lock

  workaround recursive GC calls for traces created in finalizers

- all trace handlers should be @nogc but that's currently out of
  scope b/c it requires to rewrite all backtrace and demangle code
