I have already said that, that isn't it.  In fact, the size of this
filesystem has only gone down over the last 10 months.

By trying to write nearly twice the size of a tape to a tape?  C'mon, be
serious here.

I did.  I am still on -hackers.  I spent the last 4 years working on real
problems and submitting patches for them.  Only to see them ignored.  Not
rejected for any given reason, just ignored.  So now I'm tired of being
ignored and frustrated by the long-standing and oft-reported bugs in tape
handling.  What do you expect?
