Fork()

I've been doing linux systems programming lately and was interestd in the source code for the fork() system call. I laughed when I saw this as the header:

/*
 *  'fork.c' contains the help-routines for the 'fork' system call
 * (see also entry.S and others).
 * Fork is rather simple, once you get the hang of it, but the memory
 * management can be a bitch. See 'mm/memory.c': 'copy_page_range()'
