Committed with very minor changes:
- removal of StrategyFreeBuffer() prototype
- the new message in autoprewarm used "autoprewarm: " in the log message,
which none of the other messages do - not the prettiest, but it's consistent
with what's already there
- some editing of the commit message
- some whitespace changes
