An RTEMS user has noticed that the performance of the RTEMS message
queue routines is bound by our use of newlib's memcpy routine. The
current implementation uses a byte-by-byte copy.
What would it take to get a better generic implementation? Is there one
laying around which could be used instead? I remember the old GNU/960
version did some alignment and then copied 16-bytes at a time.
