     17Although HelenOS does not have the concept of signals, it is possible to pin-point their HelenOS equivalents for some of them. For example, SIGKILL is implemented as a dedicated system call. Some of the signals are replaced (or would be) by dedicated IPC calls. For example, SIGUSR1 is sometimes used to ask a server to reload its configuration. But that is actually abusing of the signals and it makes more sense to have a special (control) interface available through IPC where it is possible to explicitly say what the server shall do. As a matter of fact, similar concept can be traced to more signals, e.g. graceful termination (SIGTERM).
