   // critical that the implementation of SampleThread does not do any of the
   // following:
   //   * Accessing TLS -- Because on Windows the callback will be running in a
   //                      different thread.
   //   * Allocating memory -- Because this takes locks which may already be
   //                          held, resulting in a dead lock.
   //   * Taking a lock -- See above.
