 * Don't know where rfork() is defined.
 * In this application, only rfork(RFNAMEG|RFNOTEG) is called.
 * In Plan 9, RFNAMEG causes the process to inherit a copy
 * of the parent's names space. The closest analogy in Unix
 * is that a child already has the same root directory as
 * it's parent so no action is needed.
 * In Plan 9, RFNOTEG causes the current process to become
 * the first in a new note group, isolated from previous
 * processes.  IT DOES NOT CAUSE A NEW CHILD PROCESS TO
 * BE SPAWNED.
 * The closest Unix analogy, is to make this process its
 * own group leader (the first 0 indicates pid of calling
 * process, the second 0 indicates process group is same
 * as pid).
