With an optimized compile (of string.c only) the speed up decreases to
only a factor of 12 :)

The "equal" case was missing one thing: if both strings are COWed copies,
the compare can be avoided too - it's equally fast then, as "not equal".
That's already in CVS.
These changes in your code show the case:
concat S0, "a"
#concat S1, "a" # <<<<<<<<
assign S1, S0 # <<<<<<<<
