This brings to mind a couple of things I've been wondering
about (but never enough to do something about myself):

- Does anyone know how long the average string in C is?
- At what point does the 4.2 locc/movc3 get faster than the
  ordinary while(*s1++ = *s2++)?
- How many percent of the strings that strcpy sees will be
  word aligned? (I have the feeling that this percentage will
  be *very* high).
- Is there anything useful that can be done with this knowledge,
  (like copying words), without first having to look for end-of-string
  with byte accesses?

Did somebody else look into these things by chance?
