* Add some more flexibility to the multiproc scheduler
There are two new options in the -threaded RTS:
-qm Don't automatically migrate threads between CPUs
-qw Migrate a thread to the current CPU when it is woken up
previously both of these were effectively off, i.e. threads were
migrated between CPUs willy-milly, and threads were always migrated to
the current CPU when woken up. This is the first step in tweaking the
scheduling for more effective work balancing, there will no doubt be
more to come.
