[PATCHv2 4a/4] Clean up 'import's

[Sebastian Spaeth]

Make imports conform to PEP8 (one import per line), remove redundant or
unneeded imports.

 I am sorry, the previous patch 4/4 would not lead to working code, I
 must have somehow missed out testing that version. I reworked patch 4
 now to work properly and split it into a 4a which reorganizes the
 imports and a 4b which actually implements the single-threading.
