To provide some data on that: popen() is presumably invoking /bin/sh,
which on my box is

$ /bin/sh --version
GNU bash, version 4.1.2(1)-release (x86_64-redhat-linux-gnu)

$ rpm -qf /bin/sh
bash-4.1.2-48.el6.x86_64

Commits

  1. Improve detection of child-process SIGPIPE failures.

  2. Handle EPIPE more sanely when we close a pipe reading from a program.
