Subject: Disable test_subprocess on LayeredTwistedIOLoop.
X-Git-Tag: v3.2.0b1~69
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=add55d515970009154645e0ff62ea12e010253dc;p=thirdparty%2Ftornado.git

Disable test_subprocess on LayeredTwistedIOLoop.

This test fails occasionally in this configuration (but strangely, the
other subprocess tests work).  I haven't been able to track it down
so just disable it for now to prevent spurious travis-ci errors.
