If stderr is closed and cargo tries to print a status message such as "Compiling", cargo can get into a hung state. This is because the
DrainState::run
function would insert the job into theactive
queue, and then return an error without starting the job. Since the job isn't started, there is nothing to remove it from theactive
queue, and thus cargo hangs forever waiting for it to finish.The solution is to move the call to
note_working_on
earlier before the job is placed into the active queue.This addresses the issue noted in #8714 (comment).
