The real kernel collects _TIF_MTE_ASYNC_FAULT into the current thread's state on any kernel entry (interrupt, exception etc), and then delivers the signal in advance of resuming the thread. This means that while the signal won't be delivered immediately, it will not be delayed forever -- at minimum it will be delivered after the next clock interrupt. We don't have a clock interrupt in linux-user, so we issue a cpu_kick to signal a return to the main loop at the end of the current TB.
