From 3e7c34140c4eb7dabd7a0c6176222df795029920 Mon Sep 17 00:00:00 2001 From: mame Date: Thu, 15 Jan 2009 17:27:31 +0000 Subject: * thread.c (rb_thread_execute_interrupts): if signal is already buffered, main thread should wait until timer thread delivers it. * thread.c (timer_thread_function): should defer delivery of a signal if main thread does not yet trap a previous one.
