Subject: [PATCH 125/310] vmstat: Prevent output truncation when piping zone
 statistics

... into other programs.

Apparently libxo (currently?) can't be trusted to flush its
internal buffer before it's full, triggering the flushing
manually works around this.

Before (sometimes):
fk@r500 ~ $vmstat -z | wc -c
    8192

After (consistently):
fk@r500 ~ $vmstat -z | wc -c
   24156
