Is the benchmark anything you can share?  I ran the glibc testsuite and
got some failures but I don't think they are due to the new memcpy.  I
am going back now and running the glibc testsuite with no changes to get
a baseline so I can verify that.  Hopefully I will have an answer later
today.

I ran some other tests like the gcc testsuite using a glibc with this
change in it and that didn't have any problems and there is the one I
sent to the list
http://sourceware.org/ml/libc-ports/2012-09/msg00007.html that also ran
with no problems.
