I would raise a proper Error exception instead of letting it crash. So that there is no "big" behavior difference

This PR should only have +setproctitle in the requirements file then ;)

The others "blank" changes (space / TAB) should be in a separate PR if you want to clean that kind of spaces / tabs ..

otherwise +1 ;)

Also : yes, I think we can keep the try: import setproctitle except .. for now if not for always. It can effectively be better to keep it in case something is wrong with the installation of this library and that it can't be imported.
But : you could/should add a warnings.warn(..) in the except clause to have an eventual trace of the actual import error.

@ddurieux : ping ?
