I think you're going over the line.  You were cc'd on all patches and
all the counter points that I wrote in this thread are repetitions
from the previous threads.  I don't remember you answering to any of
the counter points.

Can you please go into details of what kind of bugs would be
introduced by recursive removal?  I'd really like to know and be happy
to fix any actual issues but you really aren't providing useful enough
information.

Eric, chill.
