[dev] [PATCH] Change an eprintf to a die to stop child from running its own slideshow

From: David Phillips <dbphillipsnz_AT_gmail.com>
Date: Thu, 14 Jan 2016 21:02:43 +1300

The child thread was created because execlp will not return if successful.
The eprintf was placed after the call to execlp to catch any error, but the
child continued to return a (closed) fds[0], resulting in a second slideshow
being run by the child.

This commit fixes the issue by killing the child.
