It does this by telling the kernel to raise a SIGALARM after a short timeout, and clearing the timeout every time the hub greenlet is resumed. Therefore, any code that runs for a long time without yielding to the hub will get interrupted by the blocking detector (don't use it in production!). The *resolution* argument governs how long the SIGALARM timeout waits in seconds. The implementation uses :func:`signal.setitimer` and can be specified as a floating-point value. The shorter the resolution, the greater the chance of false positives. rr<N)r>r=ÚAssertionErrorr?Zdebug_blockingZdebug_blocking_resolutionZblock_detect_post)rOÚ resolutionr=rrrr µs     )NF)F)F)T)T)F)FrW)Ú__doc__rAr:rÚrer Ú__all__Úcompiler(rrrrr r rrr r rrr rrrrÚs:ü (
