wait_on_pid

This is a small utility for Linux to wait for the termination of a process.
It just polls the existence of the process in a loop, as there seems to be
no syscall to wait for a not-child process.

This was part of gentoo-vdr-scripts and then moved to a dedicated package.

It is licensed under GPLv2.
