In the old days, all Unix system calls were divided up into two groups, based on whether they were "fast" or "slow". Processes executing a "fast" system call would block, and could not be interrupted;
That doesn't really have anything to do with blocking vs. non-blocking, though. The system call blocks in both cases; the only difference is whether the kernel bothers to allow for aborting the blocked operation part way through. The calling process doesn't see any difference. -- Greg -- https://mail.python.org/mailman/listinfo/python-list
