Isn't that just a problem with Windows generally? I don't see what the method of packaging has to do with it. Also, I've seen it suggested that there may actually be a way of doing something equivalent to a fork in Windows, even though it doesn't have a fork() system call as such. Does anyone know more about this?

Cygwin emulates fork() by creating a shared mmap, creating a new child process, copying the contents of the parent process' memory to the child process (after performing the proper allocations), then hacks up the child process' call stack.
