Ability to interrupt while true end

[fonsp]

In the terminal, Ctrl+C will interrupt some code, like sleep(1000), but not number-crunching code like tight loops. For this, the Julia client has special code that checks for quickly repeating interrupt signals, which creates a "super interrupt":

In Pluto, we have the following code to repeat the Ctrl+C signal:

This sort-of works (not on Windows), but it will occasionally kill the entire Julia process.

Can you create an example of interrupting while true end using Malt.jl? Can you consistently repeat this multiple times in the same process? Maybe this can be included in the tests?

Maybe this could be included in Malt.jl API, like interrupt(worker; aggressive=true)?
