One thing you can do when running tests that use runners in subprocesses
(e.g. spawned by TestableMaster), is pass in the -e option to bin/test so that
logging in the subprocesses is enabled.  Such logging is suppressed by default
because of the noise, but enabling it lets you see if an exception occurs in a
runner that might only show up in the logs.

I don't think it does.  My first guess is that there's an exception getting
masked.
