I suppose it is possible to have two PR that have changes that depend on each other. In general this just requires refactoring... typically making a third PR removing the circular dependency.

It sounds like your policy is to keep PR around a long time, maybe? Generally we try to have ours merged within a few days, before bitrot sets in.

Sorry, my comment was unclear. I didn't mean a circular dependency, just PRs that have a chain of dependencies (e.g. PR 100 that depends on 99, that depends on 98, that depends on 97)

They're usually not around for a long time, but there can be relatively large chains if someone is quickly adding new features.
