    Description

      alexander.gorrod, based on SERVER-34082, I think cursor restart can happen fast enough that high level cursor operations like search can spin in a core: https://jira.mongodb.org/browse/SERVER-34082?focusedCommentId=1858240&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-1858240

      It would be a relatively simple change to back off and yield the processor in the case of repeated restarts in high-level cursor operations.
