What you're seeing is just the fact that lit is waiting on subprocesses (select is waiting on the pipes i suspect).
Right. Some digging revealed that it is waiting on getline_nohang.cc.tmp, a tsan test.
I see that this test has been disabled for NetBSD, due to it sometimes failing. I'm seeing the same on Linux.
How can we stabilize the sanitizer tests so that check-all can work reliably? If some sanitizer tests are so flaky, I should think they should be marked UNSUPPORTED. Who has the authority to make those determinations?
