Forgot: another problem is that just offloading to external "strlen" 
will not respect the memory segment boundaries (e.g. the underlying 
strlen will keep going even past the spatial boundaries of the memory 
segment).

Stepping back, I think this is "just" matter of writing a more efficient 
implementation that the one we have - and perhaps have some C2 
intrinsics to exploit some vectorization (or, in the future, just use 
the Vector API to do the same).
