That is good advice.

One way to end up with a "corrupted" workspace is to save it with a 
dependency on a particular package, then try to load it when that 
package is unavailable.  I'm going to see if R can handle that case more 
gracefully.

If people can describe other reproducible methods of getting a corrupted 
.Rdata it would be useful, at least for a list of "Don't do that" advice.
