I added more debug in __journal_refile_buffer() to see if the marked
buffers are getting refiled. I am able to reproduce the problem,
but I don't see any debug including my original prints. (It looks as
if none of my debug code exists) - its really confusing.

I will keep looking and get back to you.

I may try Andrew's buffer debug patch - if I get desperate.

Thanks,
Badari
