[julia-users] Is this expected behavior from nb_available?

[Dan Luu]

julia> r,_ = redirect_stdout()
(Pipe(open, 0 bytes waiting),Pipe(open, 0 bytes waiting))
julia> nb_available(r)
0
julia> println("foo")
julia> nb_available(r)
0
julia> println("foo")
julia> nb_available(r)
0
julia> readline(r)
"foo\n"
julia> nb_available(r)
4

Even if there's data available, nb_available returns 0. From the name,
I would have expected this function to return the number of bytes
available. However, since there's no documentation, either in
help(nb_available) or in the code itself, I can't tell if this is a
bug or if this is behavior is by design.
