What happened?

im testing with goleak.VerifyTestMain(m) and with the new version of testcontainers there is a goroutine leak in reaper. it looks like the terminationSignal chan wont gets closed so the goroutine hangs. but its just a wild guess here.

Relevant log output

goleak: Errors on successful test run: found unexpected goroutines:
