A single core file?

Hacking GDB so that it can handle N separate core files with N separate 
address spaces is certainly a possibility.  I suspect, however, that 
modifying the kernel so that all the information is put in a single core 
file will both be more straight forward and will provide the average end 
user with a more typical UNIX experience.
