- Defines a DTrace provider, called 'HaskellEvent', that provides a probe for every event of the eventlog framework. - In contrast to the original eventlog, the DTrace probes are available in all flavours of the runtime system (DTrace probes have virtually no overhead if not enabled); when -DTRACING is defined both the regular event log as well as DTrace probes can be used. - Currently, Mac OS X only. User-space DTrace probes are implemented differently on Mac OS X than in the original DTrace implementation. Nevertheless, it shouldn't be too hard to enable these probes on other platforms, too. - Documentation is at http://hackage.haskell.org/trac/ghc/wiki/DTrace
