I see.

Actually, using res.write() is fully compatible with
renderSkinAsString(). When you do a renderSkinAsString(), Helma calls
res.push() before rendering the skin and then returns the return value
of res.pop(). Every res.write() or res.writeln() called during skin
rendering actually appends to the StringBuffer that composes the
string.

So bug 519 is actually based on a misunderstanding, I'm marking it as invalid.
