> I often (not always) see the cpp-containre_test take up to 30-40 sec to run, the delay
seems to be in test_container_bad_address(). A normal run taks < 1sec.
> I occasionally see tsan races or asan leaks reported from the test, I believe the test's
use of the multi-threaded proactor is unsafe and there are races around the listener, but
not sure exactly what.
> I have seen the delay with libuv and epoll proactors, so suspect the problem is in the
C++ layer - or is a common bug in both proactors.
> I often see these (non-fatal) warnings with asan:
