This is how I learned to stop worrying and love c++11 =).
Ghosts of endless heap allocations have finally been exorcised. Thanks
to the nifty magic of move semantics, string will only be allocated
once on the heap. Considering that it makes a jorney across stack,
heap alloced queue, to another stack before being finally processed
I think it is kind of nifty, don't you?
Also note that for non-arg events we only copy two qwords
