We redid the installnode scheme in before 0.30, this way its more sane (and
shorter). But there is a leek somewhere in there, not serious, since we
find (and correct) the misstake.

I tried to do a small c-program that trigged the bug (like we almost always
do, see inte tests/), but I can't reproduce it. I have also tried to run
pine, still no problem.

Can you try to do a shortest complete strace that triggers the bug and put
in on a ftp/web-site ? It there is a some program that triggers the bug, it
would be even better.

Another way to find the buf is to turn on xfs-debugging and looking 
at the logs.
