The memcpy() and related functions are waiting for someone to implement emulation of misaligned string operations in the kernel, which should improve things much more than a mere factor-of-two :-), especially for short memcpy()s. However, in the meantime, there's no reason not to put these versions in (except for the licensing, of course).
