That is an interesting point actually: In my daily work I often open multiple
instances of eclipse, running with separate "workspaces" (basically different
application directories with separate configuration).

So only a single instance accesses the application directory at any time but I
can have multiple instances running. Is that possible with builder right now?
(when running from flatpak, it uses a cache for downloading/building. I
suspect that cache dir might be shared when running two instances of flatpak
builder.)
