Traditionally, the term "fork" has been used to refer to "creating a new 
process" (the traditional way of handling concurrency in Unix code)--the 
Unix syscall for this step is literally called "fork." On Unix-based 
system, process creation is extremely low overhead, so process-based 
parallelism was more common than on Windows where making a new process 
is painfully slow.

When I first saw the OP's question, I first thought he was referring to 
fork in the process-creation sense, so it's not clear to me offhand if 
he is referring to the process-creation fork or Java-framework fork.
