I don't know if this is the cause, but I noticed that if you kill svn
with a SIGQUIT (Ctrl-\ under Unix), then subsequent svn commands will
hang.

This document is nice, but you should spell-check it. :)

And what if FSFS is in an inconsistent state, i.e. if a write process
dies at a very bad moment? Or is it always consistent (i.e. possibly
with just a bad "current" file, that can easily be recovered, if I
guessed correctly)?
