You can signal a condition that is not an error, and if tryCatch hasn't 
been written to catch it, it will stop.   For example,

g <- function() {
   tryCatch(f(), error=function(e) NULL
   cat("Still running\n")

f <- function() stop("Regular error")  # This won't stop g()

f  <- function() stop(simpleCondition("I mean it!")) # This will

Of course, you can catch simpleConditions too if you try.
