Subject: leak-checker: Make output line-buffered.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9d5fc7fbdf92f6e46a8e7058391dbe19ae49c672;p=openvswitch

leak-checker: Make output line-buffered.

Unbuffered output was ideal from the viewpoint of getting the maximum
amount of output when the process was killed, but it causes a dozen or
more system calls per log entry.  Line buffering should be a reasonable
compromise.
