My apologies, but I'm not sure I followed all of that.  Can you produce
a diff against commit 8e9a68ad14655c1949b1a04d5715a5caa8c344ee that
shows the situation you think is the best so far?

} - still not sure why 36834 allocates much memory for the string test

} difference

14% is pretty substantial, but it's probably all gained back if the
function does anything significant with local variables.
