It is better to clear errors after the catch block completes rather than leave them set until the next error. This also make is possible to tell when a error is currently being handled, which a function further down the stack might use to modify its behavior. Currently this is only useful in testing, but clearing the error seems like a good idea in general. Two places used errors outside the CATCH() block. Mem context cleanup now uses a FINALLY() which is a better implementation anyway. The error handling in main() now calls exitSafe() from withing the CATCH() block.
