Limiting resource usage

[mochi-os]

I'm working on a project that runs untrusted user code, and am wondering whether Yaegi would be suitable. It's important that the user code can't bring down the machine, or cause problems for other users, so resource usage needs to be limited.

It looks like CPU time can be limited using context.WithTimeout(). Is that correct? Is this the best way to do it?

I can't find any way of limiting memory use. Is there one?

Are there any other resources I should consider limiting?
