Yeah, I was wondering that too. My code would require two scans of the
source string (one inside strlen and one in memcpy), but in much of our
usage the source and dest should be reasonably well aligned and one
could expect memcpy to be using word rather than byte operations, so you
might possibly make it back on the strength of fewer write cycles. And
on the third hand, for short source strings none of this matters and
the extra function call involved for strlen/memcpy probably dominates.
I'm happy to just use the OpenBSD version as a src/port module.
Any objections?
