When a process exits, a lot of stuff happens. One thing is that the kernel scans the process table to see if the exiting process has any children. If so, those children get a new parent. The new parent is always init which has a pid of 1.

The ppid is the current parent, not the, um, biological parent.

If you want reliably get the pid of the process that actually issued the fork, record it before the fork. But it isn't useful for anything, except maybe logging.

HISTORY

       Most of this was part of Parrallel::Runner intended for use in the Fennec project. Fennec is being broken into multiple parts, this is one
       such part.

FENNEC PROJECT

       This module is part of the Fennec project. See Fennec for more details.	Fennec is a project to develop an extendable and powerful testing
       framework.  Together the tools that make up the Fennec framework provide a potent testing environment.

       The tools provided by Fennec are also useful on their own. Sometimes a tool created for Fennec is useful outside the greator framework.
       Such tools are turned into their own projects. This is one such project.

       Fennec - The core framework
	 The primary Fennec project that ties them all together.
