Optimize shared memory usage for WaitLSNProcInfo We need separate pairing heaps for different WaitLSNType's, because there might be waiters for different LSN's at the same time. However, one process can wait only for one type of LSN at a time. So, no need for inHeap and heapNode fields to be arrays.
