   fast again
 * periodic timers have an increasing delay the longer they run
  (see dispatch_drift test). This might be due to an implementation
-  error of EVT_FILT_TIMER on windows.
-* Due to an implementation bug in gcc 4.5.1 regarding the destruction
-  of lambdas, all variables used from within a block but created
-  in the outer scope will not get properly deleted as the lambdas
-  will never be freed. Issue seems to be nonexistend when using
-  clang and can easily eradicated within VS 2010 when creating
-  lambdas on the heap instead of the stack by using an explicit new.
