I was looking at the l0dable CRT and found a few things which could be improved:
After main() exits, don't busy spin but return from the l0dable with epic_exit().
In case of an exception, don't lock up the device but also attempt returning with epic_exit(). Without this, the only way to recover would be a full reboot of the card10.
Remove some bloat by making all unused interrupt handlers weak references to the default handler.
More details can be found in the individual commit messages.
