    Here's the best performance information I can gain:
1) At the beginning, performance gain is about 35%.
2) Over time, performance gain goes to 0% on realtime data, naturally, since 
the computation time becomes most significant.
3) The real benefits are in situations of multiple plugins since an update 
will do loads of malloc/free.
4) It also helps keep the UI responsive since malloc lock contention drops and 
UI events cause loads of mallocs.

  I see both sides to the argument equally.  I'm hoping someone will make the 
call for me. :)
