>
> The MemoryPool method Release_All() was originally conceived to allow
> reuse of arena memory after being invoked, but that is not how it is
> being used -- existing call sites in PostingListWriter, SortWriter and
> SortFieldWriter expect the memory to be freed, resulting in memory
> leaks. This phenomenon is probably behind out-of-memory issues which
> may occur on lengthy indexing sessions. To fix these problems, the most
> straightforward approach is to change the behavior of Release_All() to
> free memory.
