Non-zero return code for launchpad (and possibly debian)

[mariuszskon]

If at least one download fails for launchpad, the return code is non-zero. This does not happen for other categories like rpm. This inconsistency breaks automated scripts which use the return code unless if all errors are ignored which is probably not a good idea.

$ echo $?
1

This seems to be because some of the get_all_* functions have a sleep .1 after each download, but launchpad and debian do not.
