What is the difference between quiet NaN and signaling NaN?

When the signal happens, it because the CPU hardware itself raises an exception, which the Linux kernel handled and informed the application through the signal.
The outcome is that bash prints Floating point exception (core dumped), and the exit status is 136, whi...

None of these solutions will avoid that fact that the GIL prevents CPU parallelism - they are just better ways of getting IO parallelism that you already have with threads. If you think you can do better IO, by all means pursue one of these, but if your bottleneck is in processing the resul...
