here is that example using `mkfifo`, in case it’s helpful:

```julia
julia> str = """
           abc
           def
       """
" abc \n def\n"

julia> run(`mkfifo my_named_pipe`)
Process(`mkfifo my_named_pipe`, ProcessExited(0))

julia> t1 = Threads.@spawn open("my_named_pipe", "w") do io
           println(io, str)
       end
Task (runnable) @0x000000032063aef0

julia> t2 = Threads.@spawn read(`grep "abc" my_named_pipe`, String)
Task (runnable) @0x000000032063b080

julia> wait.([t1, t2])
2-element Vector{Nothing}:
 nothing
 nothing

julia> fetch(t2)
" abc \n"

```

(I know the discussion has moved on to sockets though)
