* Note: We can use vfork() here in the no-mmu case, although
* the child modifies the parent's variables, due to:
* 1) The parent does not use the child-modified variables.
* 2) The allocated memory (in the child) is freed when the process
* exits. This happens instantly after the child finishes,
* since httpd is run from inetd (and it can't run standalone
* in uClinux).
