[squeak-dev] WideString hash is way slower than ByteString hash.

Just print this two scripts:

|s|
s := WideString with: (Character value: 16r55E4).
[100000 timesRepeat: [s hash]] timeToRun.

|s|
s := ByteString with: (Character value: 16rE4) with: (Character value: 16rE4)
with: (Character value: 16rE4) with: (Character value: 16rE4).
[100000 timesRepeat: [s hash]] timeToRun.

I've seen that "ByteString>>stringHash:initialHash" use a primitive. Could we
have such optimisation for WideString ?
