Title: Improve allocation rate of the new Lucene synchronous batch backend

When testing low-scale I couldn't detect any performance improvement, still this has a lower contention point on the work queue and keeps the allocation rate of objects much lower.

Also improves the allocation rate for the garbage created by the `ErrorHandler`, at cost of being slightly less efficient in the case there actually is an error (which is hopefully a great bargain).
