I'm no longer finding any of these problems with Ubuntu 10.10. I was able to unmount and remount SMB network shares in all the random ways I tried, with making shortcuts to subfolders on the share and clicking on those to mount the share and anything else I could think of doing, and can't reproduce this issue now.
Guess Ubuntu 10.04 will need a patch backported, or something will have to be upgraded to the version 10.10 is using?
