Shouldn't be expensive at all.  Linux uses copy-on-write (COW) when it forks.
The only thing that gets written in the new processes are a few local
variables, so the total cost is the cost in the kernel for a few new processes
(not much), plus the few non-shared pages of memory.  Overall, the cose is very
small.
