Yes, that's correct. After you mount from the smbclient command line,
there's a process that sticks around to manage the network connections
for smbfs. When a connection drops (quite a frequent occurrence), smbfs
signals the pid and then waits. I put in the timeout so smbfs wouldn't
sit forever holding the server semaphore, but I've never seen the "timed
out" message you're getting.
