      Came from investigation on BF-8367, where the awaitdata_getmore_cmd.js fails when running in parallel with compact_keeps_indexes.js. The latter performs slow operations that hold the global DB lock, and the first is expecting a getMore to time out and return a batch size of 0. Instead, the getMore fails with "exceeded time limit". Reproducible test is attached.
