        DESCRIPTION OF THE PROBLEM :
        System.arraycopy() performs brilliantly on Intel/AMD CPUs as it maps right on down to a single REP MOVS instruction. Perhaps an order of magnitude faster than the same thing in a normal loop.

        I'd like a System.arrayfill() method that could be built on a REP STOS operation.

        (Today I'm initializing buffers for a b-tree. Need to blank-fill the text buffer - a pretty common thing to do. Index efficiency is critical to DB operations, so speed matters here.)
