Agreed. Sometimes I have multiple outstanding pull requests against the same code for features different enough to be different tasks. It rarely works out well

Agreed. Sometimes I have multiple outstanding pull requests against the same code for features different enough to be different tasks. It rarely works out well but for whatever reason I don't notice it happening until the end. Alternatives are: overloading pull requests with multiple distinct tasks (bad), sitting on my hands (bad), updating the code for each PR as others are merged (bad, error prone), or creating pull requests that merge into other branches pending review (less bad but annoying to maintain). I tend to do the latter.
