42 * Signal handler on Linux
44 * Handles TERM and HUP signals and either quits or restarts the application.
46 * @TODO According to the signal(7) documentation, only "safe" functions can be called from the
47 * signal handler. We don't know how safe it is to call iApp::quit() and iApp::restart() and
48 * probably have to implement "safe" versions of these functions.

73 * Signal handler on Windows
75 * Either quits or restarts the application.
77 * @TODO Is there a similar concept of "safe" functions for Windows signal handlers?
