Bug Report

Sometimes profiler tests fail with the error bad multipart form: unexpected EOF. For example: https://github.com/DataDog/dd-trace-go/actions/runs/15781660177/job/44488540113#step:3:160

        profiler_test.go:363: bad multipart form: unexpected EOF

I haven't yet reproduced this locally. I suspect that this is not a "real" failure in the test logic. Maybe there's some small window at the end of a test where we shut down the test profiler and mock backend where the mock backend can see an incomplete request?
