* Add support for g++ 4.7 when compiling in C++11 mode. Update revision
history. Fixes #6620.
* Use the thread's private_op_queue for handlers returned by the reactor task.
This fixes a problem where signal_set handlers are not being called when the
io_service's concurrency hint is set to 1. Fixes #6657.
