Banned from remote host

[GoogleCodeExporter]

After mounting a remote filesystem, going home, going back to work the day 
after, sshfs made me ban on the remote host serving the remote filesystem.

Everything is referred to sshfs. Using OS X Snow Leopard (updated)

What steps will reproduce the problem?
1. Mount a remote filesystem H that bans your IP if you mistype the password 
too many times
2. Sleep your machine, disconnects, go home, come back the day after
3. Wake up your machine, wait some hours (<- may be not needed), go to the 
mount point of H.
4. You get an error. Try to unmount the remote filesystem. You can only with 
diskutil umount force ...

What is the expected output? What do you see instead?
The remote host has listed your IP in the denied list. 

What version of the product are you using? On what operating system?
Latest stable version on OS X Snow Leopard.

Please provide any additional information below.
The usernames on my machine and on the remote hosts are the same, but the 
passwords are not. May be the sshfs util was communicating the local password 
to the remote server.
