Comment 35 for bug 159031

@Marat BN
Normally I would agree, except NFS is ages old and does not freeze applications/the entire operating system when the Network File System goes away. The same applications that freeze when sshfs mounts go away do not freeze when NFS mounts go away.

Part of the spec of NFS is that the file system's availability is untrusted, perhaps sshfs should also make that part of the spec?

Also I'll add that this bug exhibits itself to this very day in the following scenarios:
1) Intermittent wireless
2) Flaky ISP
3) Remote end implements a timeout
4) Remote end has intermittent connectivity problems

Again, NFS handles all of these gracefully and does not freeze the system. However, using NFS over the internet is a pretty poor choice -- let alone the problem of getting someone to run NFS with authentication for you on the remote end.

I don't have the C skills to code a solution, however I'm willing to test fixes because this has been a serious problem for me since 6.06.
