No.  You'd need to also guarantee that all of the buckets sharing a
private data structure (copies or splits of a single bucket) were, as a
group, processed by only one thread at a time (and those buckets can exist
across multiple brigades even).  You'd also have to guarantee that no
buckets are added/removed from a given brigade by more than one thread at
a time.  When you add up the implications of all these things, it
basically ends up with the whole request being in one thread at a time.
