This looks like a good start for a very useful plugin. One that I would
like to include in Vim.

What I would prefer is something that works just like :make, but in the
background. It would have the same arguments as :make and use the
'makeprg' option. Only that the quickfix list is set much later.
Could call it :MakeBackground.

My wishlist:
- When using it again before the previous job is finished, prompt the
user if he wants to abort the already running job. I quite often run
:make and than realize I forgot one change.
- Open the quickfix window when the --copen argument is given.
- Give a non-intrusive message when the work is done.

Anyone who would be willing to make this work and maintain it?
