Add workaround for broken Linux pipes
Linux has an unresolved hang if you resize a pipe with bytes in it. Since there's no obvious way to detect this happening, added a workaround to disable resizing the pipe buffer if you set an environment variable. Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Rich Ercolani <[email protected]> Closes #13309
