With the current allocation strategy for brigades, not really.

Currently it's safer to call _cleanup rather than _destroy in most 
cases, since _destroy is equivalent to _cleanup but also unregisters the 
pool cleanup; so if a _destroy()ed brigade does get reused, it is at 
risk of leaking any contained buckets until the associated bucket 
allocator gets nuked.
