Differences between Kernel#sleep and Thread.stop

Question

Are:

• Kernel#sleep used without an argument, and
• Thread.stop

equivalent? If not, what differences are there?

Answer 1

i think that you are asking if calling sleep or stop within a running thread are equivalent. i would say that, yes, it's semantically the same, but they call different lowlevel functions:

stop -> rb_thread_sleep_deadly();
sleep -> rb_thread_sleep_forever();
