Tail calls can be used to increase the efficiency of loops simulated using recursion. However, not all tail calls are loops, e.g. void foo() { bar(); } A good backtrace for a crash or exception can tell me the entire call stack. Logging at that granularity (i.e. every time a function is called) is not a good idea.
