-// This structure represents a lazily initialized static usize value. Useful
-// when it is preferable to just rerun initialization instead of locking.
-// Both unsync_init and sync_init will invoke an init() function until it
-// succeeds, then return the cached value for future calls.
-//
-// Both methods support init() "failing". If the init() method returns UNINIT,
-// that value will be returned as normal, but will not be cached.
-//
-// Users should only depend on the _value_ returned by init() functions.
-// Specifically, for the following init() function:
-//      fn init() -> usize {
-//          a();
-//          let v = b();
-//          c();
-//          v
-//      }
-// the effects of c() or writes to shared memory will not necessarily be
-// observed and additional synchronization methods with be needed.
