Yes, this is a frequently attempted project that slowly makes progress
over time. I think that Utkarsh has gotten somewhat close to a
workable solution, but there were some design flaws in his approach
for task stack protection (mainly, iterating over all the tasks) that
are still lingering.

There could be enough work here to pick up from his progress. The
major issue would be figuring out what  the final state of his code is
in, and to dig in to the design and implementation details to write a
concrete proposal how to bring task stack protection to a production
state. There may be other directions to consider as well, such as
improving the risc-v MMU support perhaps.
