The flip side, though, is that the test no longer reflects the production code as well. That is, in the real world we'd still call exit() from a thread. That obviously works OK now (modulo LSan), but if we ever had a regression where that left us in an inconsistent state, we'd be less likely to notice it. Feels kind of unlikely in practice, though. I dunno. I guess the real least-bad thing is seeing if LSan can be fixed to handle this atomically. I haven't even reported it there. If do go with "--threads=1", I suspect several tests in that file need it. -Peff
