--- NEW FILE: condition-wait-sigcont.lisp ---
;;;; prior to sbcl 0.9.15.39 a SIGSTOP and SIGCONT while waiting
;;;; on CONDITION-WAIT caused a spurious wakeup.

;;;; This software is part of the SBCL system. See the README file for
;;;; more information.
;;;;
;;;; While most of SBCL is derived from the CMU CL system, the test
;;;; files (like this one) were written from scratch after the fork
;;;; from CMU CL.
