Unexpected sequence of output on Linux/F# 3.1/Mono 3.12.0 (expected "foo" to be output after the numerical sequence)

boom.fsx

let seqGen a b =
  seq {
    yield! seq { a .. b }
    raise (System.UnauthorizedAccessException("foo"))
  }

try
  seqGen 1 10
  |> Seq.iter (fun x -> printf "%A " x)
with
  | :? System.UnauthorizedAccessException as uae -> eprintfn "%A" uae.Message; exit -1
exit 0

"foo"

With s/eprintfn/printfn/ on line 11, the output is ordered as expected.

Seems like processing of stderr has higher precedence than stdout in the terminal subsystem in Linux.
