[opensuse-buildservice] --disable-cpio-bulk-download fails with OBS

A few years/months ago I always called osc build with --disable-cpio-bulk-download to workaround some bug in OBS or osc that affected me at that time. Since a few days my osc wrapper hangs when doing 'osc build', when it tries to download packages for the chroot. Sometimes it downloads no package at all, or it hangs after downloading a different number of packages. Removing that option fixies it. Is that option still supported by OBS? Olaf
