actually, I'd like to leave this block in. Did the presubmit tests make you
remove it?

If so, I suggest we update a different bot like, say, "Linux Tests" on
chromium.linux
to use "none" instead of "swarming_gn_release_bot". 

[Sam Clegg, 2015/11/21 00:43:46]

Yes, presubmit told me to do it.

Done.
