Start checking for a few possible resource exhaustion scenarios for explorer (#2793)

Browse Source 
I couldn't figure out a way to actually hit a reasonable out-of-memory case once I add the maximum interpreter step count. However, the step count limit seems more important.

I've moved the todo stack limit out of function calls because there are plenty of ways to build up the todo stack without any function calls.

Fixes #2791
