Motivation:
`scavengeSome()` has a corner case: when setting `cursor` to `head`, `this.prev` may point to the tail of the `WeakOrderQueue` linked list. Then it's possible that the following while loop will link the tail to the head, and cause endless loop.
I made a reproducer in 36522e7b72 . The unit test will just run forever. Unfortunately, I cannot change it to a unit test because it needs to add some codes to `scavengeSome` to control the execution flow.
Modification:
Set `prev` to null when setting `cursor` to `head` in `scavengeSome`
Result:
Fixes #6153.

How to build
For the detailed information about building and developing Netty, please visit the developer guide. This page only gives very basic information.
You require the following to build Netty:
- Latest stable Oracle JDK 7
- Latest stable Apache Maven
- If you are on Linux, you need additional development packages installed on your system, because you'll build the native transport.
Note that this is build-time requirement. JDK 5 (for 3.x) or 6 (for 4.0+) is enough to run your Netty-based application.
Branches to look
Development of all versions takes place in each branch whose name is identical to <majorVersion>.<minorVersion>. For example, the development of 3.9 and 4.0 resides in the branch '3.9' and the branch '4.0' respectively.
