This case is described as the use case #2 in the PEP, so it is supported. As written in the PEP, if you want to be notified of the signal, set a signal handler which raises an exception. For example the default signal handler for SIGINT raises KeyboardInterrupt.

Wait - sigint? Does this mean that (unless the application adds a signal handler) keyboard interrupts will be in effect ignored while in a system call? I'm not sure I like that - I'd rather Ctrl-C always interrupted the program. Specifically, in one-off scripts that don't take care to handle all errors appropriately and just show the traceback...
