It's possible to set a read only FD to signal.set_wakeup_fd(fd) Since write call[1] inside 'trip_signal' return code is ignored, no error will be raised. An untested solution is to call fcntl in this FD to check presence of write flags. 1 - http://hg.python.org/cpython/file/fb90e2ff95b7/Modules/signalmodule.c#l187
