stringStream mallocs on initialization, and there are a few uses in ObjectSynchronizer which is only used in case a guarantee fails which would benefit from being guarded.
For example the stringStream ss in om_alloc is completely unused, but still accounts for roughly 30% of the instructions retired by that method.
