Infinite non-cyclic recursion causing StackOverflow leads to crashed Julia session

Infinite non-cyclic recursion causing StackOverflow leads to crashed Julia session.

I think this is because it throws another stackoverflow trying to print the exception's Salsa Stack.. 😅 Maybe we want to special-case the exception printing to not print the whole thing in the case of a StackOverflow, and/or to have some cut-off for the stack depth we'll print?

Or figure out how to do it in a loop instead of recursively or something?

Here's an example crash:

julia> using Salsa

julia> @derived foo(rt, x) = foo(rt, x+1)
foo (generic function with 1 method)

julia> rt = Runtime()
Salsa.Runtime(Salsa.DefaultStorage(0, ...))

julia> foo(rt, 1)
