Ah, while I thought it may be an compile option this didn't fit to the way it was mentioned in the man-page, so I neither checked debian/rules nor debian/changelog. > I'd be happy to prepare an upload enabling threading for experimental, > though.

The main point is get a program that offers it. (Actually I'd need a backport to stable. ;-) (Cc'ing the original RFP again because of this and the following paragraph.) Another option would be to use this hack called ChopZip[1] which actually chops the to be compressed file in parts and then concatenates the compressed parts together. Said to work with gzip, bzip2, lzip and xz.
