489 // To use Atomic::inc(jshort* dest) and Atomic::dec(jshort* dest), the address must be specially

   490 // aligned, such that (*dest) occupies the upper 16 bits of an aligned 32-bit word. The best way to

   491 // achieve is to place your short value next to another short value, which doesn't need atomic ops.

   493 // Example

   494 //  ATOMIC_SHORT_PAIR(

   495 //    volatile short _refcount,  // needs atomic operation

   496 //    unsigned short _length     // number of UTF8 characters in the symbol (does not need atomic op)
