Can you reference the corresponding quinn PR? I think it's best to leave feat-multipath pointing at main-iroh of quinn for now and get the fix merged there first. Otherwise things will get very confusing.

This is the quinn PR in question n0-computer/quinn#233
But given the discussion, we can drop it here, bump the timeout to 3.5 sec on the transfer example for now and maybe leave a note and do that one in a follow up.

This also allows us to go back to main-iroh

so are you updating this to only the moving of where the closing is set and closing the other PR? /me confused on how actionable this is right now.
