listdir hangs indefinitely

[dhirschfeld]

Just trying to use fs.sshfs to access an sftp server but I'm finding that listdir is hanging indefinitely.

I've tracked it down to this line:

fs.sshfs/fs/sshfs/sshfs.py

Line 303 in 33f981b

uname_sys = self._exec_command("uname -s")

...which calls the paramiko SSHClient.exec_command without a timeout argument:

fs.sshfs/fs/sshfs/sshfs.py

Lines 294 to 295 in 33f981b

	_, out, err = self._client.exec_command(cmd)
	return out.read().strip() if not err.read().strip() else None

Unfortunately, for whatever reason this seems to never return for me.

Fixed in 44faa73.

I'm not ignoring for eventual socket errors, but raising them, since this is what the rest of the functions do (handle filesystem logic, but pass network errors transparently).
