-When writing to a closed pipe, which happens with simple
-
-    seq 99999 | grep -v xxx | head -1
-
-the write() function will return an EPIPE error. The kernel also sends
-SIGPIPE to the process, which by default kills it.
-
-As the signal delivery is not immediate, grep may see EPIPE and report
-it as an error, which is annoying, especially on Android where this
-timing issue is encountered a lot more.
-
-See http://debbugs.gnu.org/cgi/bugreport.cgi?bug=23267 where it has
-been suggested to silently ignore EPIPE. That was in the context of
-SIGPIPE being ignored, but this should probably also been done to
-avoid timing issues. Feedback has been sent to the above issue and
-is awaiting mailing list approval.
