dequed

API

Not decided, probably going to change it to match the other implementations for drop-in replacement.

Performance Notes

Seems to be the fastest Deque implementation using Linked Lists.

The double-ended-queue module seems to be using a circular buffer. I think I can push the performance a bit further by using object pooling, but I want to make that optional without affecting the performance too much.

Somehow having an object pool in place seems to hurt my performance more than anything...
