# SIGPIPE

When a Go program writes to a broken pipe, the kernel will raise a
SIGPIPE signal.

If the program has not called Notify to receive SIGPIPE signals, then
the behavior depends on the file descriptor number. A write to a
broken pipe on file descriptors 1 or 2 (standard output or standard
error) will cause the program to exit with a SIGPIPE signal. A write
to a broken pipe on some other file descriptor will take no action on
