Summary: The patch reduces the contention over prepared_mutex_ using these techniques: 1) Move ::RemovePrepared() to be called from the commit callback when we have two write queues. 2) Use two separate mutex for PreparedHeap, one prepared_mutex_ needed for ::RemovePrepared, and one ::push_pop_mutex() needed for ::AddPrepared(). Given that we call ::AddPrepared only from the first write queue and ::RemovePrepared mostly from the 2nd, this will result into each the two write queues not competing with each other over a single mutex. ::RemovePrepared might occasionally need to acquire ::push_pop_mutex() if ::erase() ends up with calling ::pop() 3) Acquire ::push_pop_mutex() on the first callback of the write queue and release it on the last.
