Priorities are implemented, but still undergoing design changes, in the
thread_dev branch.  The timer, if I understand what you want, is trivial
to implement portably with the current Boost.Threads interfaces, but I do
plan on addressing this as well.

Not that useful, IMO.  Usually you want to set a specific priority, and
this interface would require several calls to do so.  Further, these calls
can fail, so should probably have bool return types.

Difficult to design portably, but possible.
