--- Comment #1 from Florian Weimer <fweimer at redhat dot com> ---
Do we actually need the proc_file_chain variable anymore?  I think CLOEXEC
takes care of closing all of the descriptors: The parent pipe end always has it
set, and the child end loses it only in the child process, so pending child
pipe ends from other threads have CLOEXEC set as well.
