0005-Make-the-collector-build-with-threads.patch

Make the collector build with threads

In an extremely limited way for now:

• No extra threads More threads always lead to exactly one borked thread that's stuck in no man's land, doing who-knows-what, and definitely not responding to signals. However, the APIs are there and they work, so they can be used to make threads.
• No fork handling Seems borked for unknown reasons.
