-----------------------------------------+----------------------------------
 I was trying to figure out what part of the bonnie++ benchmark was failing
 on tahoe (via sshfs), so I mounted the sshfs interface and ran:

 {{{
 > bonnie -d ./mnt -s 100m  -n 0  -r 50m
 Writing a byte at a time...done
 Writing intelligently...done
 Rewriting...done
 Reading a byte at a time...done
 Reading intelligently...done
 start 'em...
 ^C
 Can't read data from ITC pipe.
 Can't read from pipe, expected 32, got -1.

 }}}

 It hung for a while after "start 'em", so I checked the flog and there was
 no activity, so I hit Ctr-C, which gave me those 2 errors and then the
 interface hung.

 I had to kill -9 sshfs to get everything to free up, then I re-mounted the
 sshfs interface, did a:

 {{{

 > ls ./mnt
 Bonnie.3520

 > rm ./mnt/Bonnie.3520

 }}}

 And it hung on the 'rm'.

 I had flogtool running for the 'rm', and the output was (below).

 After restarting the tahoe client process and then reconnecting via sshfs,
 I was able to delete the file.
