Closes #317. The httptest server cancels the context after the connection is closed, but if a connection takes a long time to close, the request would never end. This applies a context to the entire listener that cancels on test cleanup. After discussion with @bryphe-coder, reducing the parallel limit on Windows is likely to reduce failures as well.

Nice catch... It's surprising that this is necessary, but glad you found it.

Per our discussion in slack - we may want to consider bumping the cache in one of these ways:
- Adding a
-v0-parameter that we can bump to invalidate the cache - Using
matrix.osinstead ofrunner.osfor the cache here - that will usewindows-2022instead ofwindowsfor the cache key

Ahh that's a great idea! Changing now.
