Change subject: core: Allow force re-election of a specific host as SPM
......................................................................
Patch Set 2: I would prefer that you didn't submit this
(5 inline comments)
As far as I get it, you're basically sending a StopSPM command with an
additional parameter, the ID of the host you want to use for the SPM.
If it succeeds - all is well.
If it doesn't, we try the next host. I'm not sure what the semantics of sending
host1 and getting a new SPM on host2.
Should this be marked as a success?
Giving -1 to indicate this question should be discussed (possibly on
engine-devel, as Michael suggests).
(Also, some nitpicking inline)

Should we?
