This has, in fact, happened before. One of the reasons that the unallocated spaces are listed on the RBL.
This topic comes up every now and then. I've searched the ARIN site and found some very outdated lists (some as old as 1996, but none newer than Feb, 1998). I've searched the archives, but no one seems to have an answer - except you. How do you tell what is and what is not allocated?
Well, there is the problem of where to look. There is a pretty comprehensive list of the delegation status of blocks at the /8 level that is pretty accurate. I suspect that the RIRs can provide pretty good detail for the recent (1996 and later) delegations. The historical delegations are -much- harder to track. I've been spending some time on clearing up detail on older /8 blocks and this data may make it into the publicly visable registries if they want it. 128.0.0.0/8 is done and I've got most of 192.0.0.0/8 complete. -- bill
