Regarding the use of Spirit within Boost.Log: If I get it right, 
spirit::karma supposed to be extremely fast in serializing. In another 
thread I read that one of the performance issues is the serialization of 
DateTime (http://lists.boost.org/Archives/boost/2010/03/162905.php).

Would it make sense to use karma here to speed things up?
