I assume you mean to add ReorderBufferTXN entries to the binaryheap

ReorderBufferTXN entries are removed and deallocated once the
transaction finished. How can we efficiently remove these entries from
binaryheap? I guess it would be O(n) to find the entry among the
unordered entries, where n is the number of transactions in the
reorderbuffer.
O(log n) for both functions: binaryheap_remove_first() and
binaryheap_remove_node(). I didn't read your patch but do you really need to
free entries one by one? If not, binaryheap_free().
