Raymond, looking at your patch, can we assert that deque->leftblock is never equal to deque->rightblock? If not, you need to use memmove() instead of memcpy(), which is unsafe for overlapping arrays.

It is not clear to me that this invariant is true. At the very least, an assertion should be there to protect future refactorings.
