Given that TestTraceManyStartStop was running for less than a second before it timed out, it seems likely that some other test in this package is too long/expensive and should be skipped when testing.Short() is true.

https://storage.googleapis.com/go-build-log/33992f4a/openbsd-amd64-72_ed2d35db.log shows a timeout with a long running time in TestTraceStressStartStop/Default.

That one is a bit strange because it seems to show a go run command with a lot of goroutines in buildActionID, waiting on the results of go tool compile -V=full. 🤔

These tests do invoke the compiler, but only on very small programs. Still, if that's a problem, I can restructure the tests to group all the programs together like src/runtime/testdata/testprog. (Originally there weren't enough of them for me to consider that necessary, but maybe now there's enough that it causes problems...)

It seems odd to me that the go run command stalled for that long on the builder in the first place. I'm not sure what's going on there. Linking can be expensive, but that go run command doesn't seem to have even gotten that far. I wonder if that's another symptom of a bug in the kqueue netpoll implementation...

Woooaaah... that is way longer than that test should ever take. That could be a deadlock, perhaps. I'll try to reproduce.
