Koichi Sasada 36da0b3da1 check interrupts at each frame pop timing. ... Asynchronous events such as signal trap, finalization timing, thread switching and so on are managed by "interrupt_flag". Ruby's threads check this flag periodically and if a thread does not check this flag, above events doesn't happen. This checking is CHECK_INTS() (related) macro and it is placed at some places (laeve instruction and so on). However, at the end of C methods, C blocks (IMEMO_IFUNC) etc there are no checking and it can introduce uninterruptible thread. To modify this situation, we decide to place CHECK_INTS() at vm_pop_frame(). It increases interrupt checking points.
