Had you only read to the end of my mail..... You are deliberately
ignoring part of what I wrote and the blame me for the remainder being
I clearly stated that there are cases where "free" can raise a valid
exception, and that the developper has to know this cases, and handle
them (with nested try blocks).
But I also wrote that (for me) the rule is that most "free" are not
expected to do so (that may of course be totally different in your code).
