FAIL: test_c_global_variables_dwo (TestGlobalVariables.GlobalVariablesTestCase)
Test 'frame variable --scope --no-args' which omits args and shows scopes.

Logs are a bit scarce, but they seem to indicate this was caused by a failed
adb connection while attempting to install liba.so.

Normally, the TCPSocket::Connect should be followed by a bunch of socket
traffic. Instead, we seem to be closing the socket without sending any data.
It's hard to tell what to do at the moment, but I'll try to add more logging to
better understand the problem..
