--- Comment #13 from David Krauss <potswa at mac dot com> 2010-10-01 12:19:26 UTC --- (In reply to comment #12) I haven't decided on that. It's a performance improvement but rather ugly. I was thinking, if lseek(0,cur) can alter the behavior of a filesystem, it must not be that fast. But it didn't, so I'm not really inclined to pursue this further.
