I have a program that uses an io_service to queue and execute function calls
sequentially within its own thread. Other threads call io_service::post to
queue small tasks, but every so often a large task is posted to the
io_service. In my case, this large task is time-sensitive and must take
priority over all other tasks. Is there a way to push that large task to the
front of the io_service's queue, so I can guarantee it gets completed as
soon as possible?

A simpler way of asking my question: is it possible to prioritize an
io_service queue? How?
