   HypothesisWorks/hypothesis#4364 noted a performance regression in hypothesis. Not sure what version that was but IIRC it's fixed now.

   We might want to use something like pytest-timeout to limit the runtime of those tests regardless.

   Currently running at > 30 mins and counting over at https://github.com/zarr-developers/zarr-python/actions/runs/14883916292/job/41798353654?pr=3041. Would be great if someone can think of a way to speed up the hypothesis tests.

   I can take a look next week. One option is to run the stateful tests (which are the slowest one) only nightly.
