Yes, primarily networking tests. Also things like signals and threading.

Anything that connects to a remote host is definitely flaky. Most of
the tests that connect to localhost are flaky for one reason or
another. One reason used to be port allocation. That is mostly fixed
The big reason that most tests fail now is EAGAIN or some other error,
typically on non-blocking sockets. Switching to blocking sockets
isn't really a great option since the tests are much more likely to

The information happens to be encoded in the URL. The URL above is for trunk.

That is the landing page for all the info you could want. Well,
mostly. The logs often don't really have enough info to debug the
problem. In that case, it would be better to add more debugging to
