Indeed, hence "*limit* EINTR occurrences" :-)

asyncio uses a wakeup FD, registered in the main event loop: so as
soon as a signal is received, the main loop will wake up and run the
signal handler. So this would only be a problem if you were doing a
blocking syscall from the main loop thread, which would be a really
bad idea anyway.
