There are many subtleties when recovering from errors in the event loop, and coldboot requires internals to drain the receive buffer as synthetic uevents are being arranged.

This is done by both systemd sd-device and AOSP ueventd to improve robustness. Rosa OS will still handle ENOBUFS via coldboot but a big buffer should mitigate this as well.

This requires the caller to arrange for a coldboot to happen, some time after this error is encountered, and to resume event processing.

These are not possible to cover outside integration vm. Extreme care is required when dealing with this method, so keep it simple.

This runs in the Rosa OS init, so recover as much as possible, as otherwise it is likely to require a full system reboot to resume event processing. The caller is responsible for reporting the error.
