I'm seeing the same behavior here. libreoffice-3.6.6.2 on a mostly stable system. btrfs on lvm on dmcrypt on a hybrid disk. kernel 3.7.5 pf-sources. I don't think is has anything to do with the file system or hardware. make is eating 200M memory and uses 100% CPU, not mkdir. I guess the script is just buggy. Regards, Florian Philipp
