- rc: fix segfault when SIGINT is received Save the value of `runq' at the start of the function, so that the `pc' update at the end does work on that original value, and not on a probably modified value of `runq'. fixes #14 http://code.swtch.com/plan9port/issue/14/ http://codereview.appspot.com/104066
