Status in OurDelta - Builds for MySQL: Confirmed

Bug description:
When long_query_time is really small, the slow log will also see queries that are not actually executed, for instance because of a syntax error. Naturally this is not desirable behaviour.

The probable cause is actually likely to be with the original slow query log code and not with the microslow patch as such; with second-granularity, no syntax error query would ever take longer than a second to get through the parsing stage....
