[Discuss-gnuradio] features/mp-sched has been merged into the trunk

[Eric Blossom]

I just merged the SMP scheduler code (features/mp-sched) into the
trunk [9336].  Outside of the dependency on boost 1.35 or later (see
below), things should continue to work without changes, but will be
faster on SMP machines.  This has been tested on Linux and NetBSD, and
is believed to work on OS/X (though I haven't received confirmation
yet).

This change set also fixes some outstanding bugs, including removing
the "single gr_top_block" restriction.

As always, please let me know if you run into any problems.

The trunk now depends on boost 1.35 or later, and most distros aren't
shipping this yet.  This wasn't done lightly, but 1.35 introduces some
very nice features for managing threads, which greatly simplified the code.

For information on building boost from source, see

Boost 1.36.0 is the latest release.  It's what I'm using.
