[sldev] PATCH for SNOW-203 (162)

[Aleric Inglewood]

I attached SNOW-203-v2.diff which addresses the weird name of the function
(renamed from 'forceImmediateUpdate' to 'bumpToMaxDecodePriority').
The function names now are what they should have been imho.

I intend to commit this in a few days unless someone has serious objections.

PS Note that ThickBrick told me he applied the patch wrongly, which is why
it didn't work for him. He'll re-test it. I also looked at Tayra's concerns but
really don't see how this patch can possibly be wrong, apart from that I
don't like to 'guess' in the first place :p. I also cannot reprocude any
failure anymore. Maybe the patch is indeed such that when applied it
changes the wrong hunk...
