A tricky one - if you use wget with auth, it works like this:
- you run wget in foreground
- No other process can start until you enter password
- wget asks you for password
- you input password
- you wait for download
Is it possible to make wget (or similar tool) background after #4? Note - if you run wget in background (#1), of course it foregrounds for #3, but #2 is then violated.
