'rm' via sftp+sshfs

[bj0]

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.
