In this BF, we identified a task that regularly takes too long to run (close to the 6H timeout). Although we are temporarily mitigating the timeout risk (by changing the timeout from 5H to 6H), a better long-term fix is to parallelize the subtasks within the problematic task, thereby reducing total wallclock execution time.

The task in question is "benchmarks", defined here. More details available in this Slack thread.
