-/**
- * Crash Monitor
- *
- * Monitors execution of a program to detect possible crashes. After
- * program termination, the monitor can be queried during the next run
- * to determine whether the last run exited cleanly or not.
- *
- * The monitoring is done by registering and listening for special
- * notifications, or checkpoints, known to be sent by the monitored
- * program as different stages in the execution are reached. As they
- * are observed, these notifications are written asynchronously to a
- * checkpoint file.
- *
- * During next program startup the crash monitor reads the checkpoint
- * file from the last session. If notifications are missing, a crash
- * has likely happened. By inspecting the notifications present, it is
- * possible to determine what stages were reached in the program
- * before the crash.
- *
- * Note that since the file is written asynchronously it is possible
- * that a received notification is lost if the program crashes right
- * after a checkpoint, but before crash monitor has been able to write
- * it to disk. Thus, while the presence of a notification in the
- * checkpoint file tells us that the corresponding stage was reached
- * during the last run, the absence of a notification after a crash
- * does not necessarily tell us that the checkpoint wasn't reached.
