What will happen is that if you have the max for 32bit uints number of  
frozen tracks, ardour will wrap around and replace your first frozen  
version with the new version, instead of giving an error message. As far  
as I understand the code.
Unlikely, but you crazy 64bit folks may want to do more than 0xFFFFFFFF  
frozen versions of the same track.
