I don't think he is trying to initiate a continuation in the child  
from the parent
or vice versa (right Clifford?). If you create a continuation before  
the fork, and then fork,
both the parent and the child process will have duplicate copies of  
the continuation.
You've cloned the process and everything inside it including the  
continuations.

Having the child resume its continuation or the parent resume its  
continuation
should be ok. I'm surprised that it didn't work.  It is either an  
oversight or something
about the way Ruby implements fork (exceptions or IO?), but I don't  
think it is an inherent problem in
the concept.
