[concurrentbatch] skip size==0 requests #208

Closed jmacd closed 3 months ago

jmacd commented 3 months ago

Size=0 requests could get stuck in the concurrent batch processor if there are not other requests traveling through. This bug was able to cause test failures when race detection is enabled.

Fixes #206
