In particular the case of "I need to do this cleanup before the program terminates" is much more general than Posix and signals. For example a library installing a handler for SIGINT is the wrong thing to do (and not just because it's not very modular) but because the very decision about whether SIGINT is going to kill the process or not is not for the library to decide. What it needs is to be thrown an exception when the process does decide that it's going to terminate.
