--- Comment #38 from Michael Godfrey <godfrey@....stanford.edu>  2010-04-30 06:02:32 ---
Just a couple of comments on the posts above:

1. In our environment, home directories are NFS mounted,
   so vi cannot read .vimrc.  It appears that this is where
   it hangs.  The important thing is that nothing
   appears on the user's screen after typing vi. 

2. We do not have an XFS filesystem, so I cannot comment on
   whether these problems exist for XFS.

3. The comments indicate that, as usual, there is more than
   one problem.  I am hopeful that the ext4 problem that Eric
   Sandeen is fixing and proposed fixes for sync will make
   a significant difference.
