debugview++test 'LineBufferTest2' locks up the GUI temporarily

[janwilmans]

the test outputs 3x17.000 lines during the test, this completely locks up the UI while the test is running.
There is also another symptom visible:
a std::cout << msg << std::endl is not 'flushing' until the end of the test, so there is now way to tell the user to wait

I think its a feature/bug that was always in boosttestui (large amounts of data in the logwindow seem to cause delays).
However, the behaviour of BOOST_TEST() seems to have changed:

0.014863 DebugView++Test.cpp(276): info: check line.time == 42.0 has passed
0.014870 DebugView++Test.cpp(277): info: check line.systemTime.dwLowDateTime == 43 has passed
0.014878 DebugView++Test.cpp(278): info: check line.systemTime.dwHighDateTime == 44 has passed

it is outputting a line now for every PASSED test... this seems to me, to be irrelevant information (I would mainly want to know about failures, not passed tests :), aside from the summery of course

[janwilmans]

I was probably wrong, the problem is maybe that the test is started with --loglevel=all with outputs A LOT of stuff, and this does not seems to go well with the log-window (maybe every single message is handled on the UI thread?
