Re: [PATCH 0/6] CLONE_FD: Task exit notification via file descriptor

This patch series introduces a new clone flag, CLONE_FD, which lets the
caller handle child process exit notification via a file descriptor rather
than SIGCHLD.  CLONE_FD makes it possible for libraries to safely launch
and manage child processes on behalf of their caller, *without* taking over
process-wide SIGCHLD handling (either via signal handler or signalfd).

FYI, the matching use of this feature in Qt can be found at:

	https://codereview.qt-project.org/108455
	https://codereview.qt-project.org/108456

The forkfd.c file this modifies aims at implementing the semantics of CLONE_FD 
for the fork case when support for CLONE_FD is missing in the kernel.
