Subject: Fix default IOLoop in Subprocess.
X-Git-Tag: v3.1.0~5
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d088cb6973db73b5eb12812c440e8245f3fb4fdf;p=thirdparty%2Ftornado.git

Fix default IOLoop in Subprocess.

Exit callbacks would fail for Subprocesses that did not explicitly
set an IOLoop.
