bug#8023: Why can't one run more than one dired-do-async-shell-command at once?

[jidanni]

Why can't one run more than one dired-do-async-shell-command at the same
time?

Why not allow more than one?

  shell-command: Shell command in progress

What if bash was also that way?

If it is a matter of what buffers it is writing to, then append their
names with <2> etc. or a process ID.

  & runs the command dired-do-async-shell-command, which is an
  interactive compiled Lisp function in `dired-aux.el'.

  It is bound to &, <menu-bar> <operate> <async-command>.

  (dired-do-async-shell-command COMMAND &optional ARG FILE-LIST)

  Run a shell command COMMAND on the marked files asynchronously.

  Like `dired-do-shell-command' but if COMMAND doesn't end in ampersand,
  adds `* &' surrounded by whitespace and executes the command asynchronously.
  The output appears in the buffer `*Async Shell Command*'.
