It includes patches from Paolo Bonzini which adds generic uatomic ops support for architectures not explicitely supported by liburcu. So, basically, we get ia64 and alpha support for free when the compiler used is gcc 4.0-4.5. It comes with a huge cleanup and refactoring, removing duplicated code. There is also a small bugfix in urcu-bp, the User-Space Tracing (UST) version of the library (this flavor does not require explicit reader thread registration/unregistration). There was a garbage collection bug that did not set the old per-thread counter to 0, which could cause an assertion to trigger if the entry was re-used by a newly spawned thread.
