I got an interesting (hopefully) idea that might solve your problem and also 
other similar ones.

What if it was possible to clone a process, with all it's data? If there are 
no external references (large binaries that need to be reference counted, 
file handles, links to other processes and so on) then this could be faster 
and cheaper than just starting a process and copying the data as Erlang 

Of course, the problem is how to ensure there are no such external 
references, but maybe someone else has a solution to that.
