host_alarm_handler() is invoked from the signal processing thread (currently the iothread). Previously we did processing in a real signal handler with signalfd and therefore needed signal-safe timer code. Today host_alarm_handler() just marks the alarm timer as expired/pending and notifies the main loop using qemu_notify_event(). Therefore these outdated comments about signal safety can be dropped.
