gh-114914: Avoid keeping dead StreamWriter alive - #115661
Merged
Merged
Conversation
In some cases we might cause a StreamWriter to stay alive even when the application has dropped all references to it. This prevents us from doing automatical cleanup, and complaining that the StreamWriter wasn't properly closed. Fortunately, the extra reference was never actually used for anything so we can just drop it.

Like in the other PR, I believe that one or two sleep(0) should deterministically reach the state you're waiting for?

Three, actually.
But I'm cautious about this change. Right now, it seems to require three. But someone might change something so that tomorrow this requires four. At which point this test will start reporting "ok" even if everything is broken. :/

I think adding a future to wait on could give something more reliable in this specific case.
