Klaus is right. However, we could kind of officially support it by adding the code as a branch on GitHub and keeping it up to date with master (if not continuously, at least every once in a while or after releases). Klaus, what do you think?

Hi

IMO the main reason is that this patch fixes one important multi-threading issue
expecially when using QuantLib in C#/Java, namely the Observer pattern. But the
modified Observer pattern implementation is based on boost::signals2 and
therefore comes with a performance penalty and the rest of the implemenation
needs a dirty trick via boost shared pointer debug hook to work.

Therefore I'd only recommend using the patch if you really need it and I'd
prefer to not "pollute" the official QL release.
