I've noticed that when configuring test/format with many threads and checkpoints enabled, workloads tend to spend a lot of time with only a single thread inside the WiredTiger library.
For example, if I run test/format with the following configuration:
I regularly see stacks from pmp like:
If I disable checkpoints I see more threads running more of the time.
This may be "works as designed", but I think it'd be better to have more threads in the WiredTiger library than less.
