Outdated:
In WT-11121, we decided to change the op_timer and operation_timeout configurations so that they would only be used for transactional operations as it didn't really make sense to be able to rollback operations that were not within a transaction.

However, it may still be useful to have some sort of operation_timeout feature for operations that are not necessarily transactional, e.g. pre-fetch. For example, in WT-12816, it would be useful for pre-fetch worker threads to be able to timeout if they cannot proceed due to being blocked by eviction.

Re-visit this design decision and figure the best way for timeouts to exist in the API.

EDIT:
WT-12977 reverted the logic regarding the timeout code coming from WT-11121. However, prefetch threads are still not allowed to be pulled into eviction. This ticket should investigate if they should and if yes, put in place mechanisms to allow it in a safe manner.
