Sorry, I don't see the test failure.  Based on the comments in 
libio/genops.c, I think there is an expectation that even with locked 
stdout, exit does not block.

In other words, if this test times out for you, this is a genuine bug, 
not an issue with this test.

I may be missing something, but in that case, please elaborate.

Thanks,
Florian
