Found by Stefan Hajnoczi: There is a race in kvm_cpu_exec between checking for exit_request on vcpu entry and timer signals arriving before KVM starts to catch them. Plug it by blocking both timer related signals also on !CONFIG_IOTHREAD and process those via signalfd. As this fix depends on real signalfd support (otherwise the timer signals only kick the compat helper thread, and the main thread hangs), we need to detect the invalid constellation and abort configure.
