there are still many running jobs though, is this a new intermittent build failure?

[jdm]

Something in these changes is causing the multiprocess tests that run the eventsource/ directory to have a bunch of unexpected results.

[jdm]

I see it - wptserve was updated for python3 compatibility, and we run our multiprocess tests with python2 to verify that that codepath keeps working even as we transition most of our tests to running with python3.

[jdm]

I lied - we run the eventsource tests twice, once with python2 and once with python3. It's the python3 job that has the failures.

[jdm]

Filed web-platform-tests/wpt#23436 and switched us to run the url tests instead of eventsource in the meantime.
