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?
