-     No, I'm not proud of this.
-     We have to use DarwinSigReturn to work around an OSX G5 bug.
-     To make matters worse, Darwin loses track of the MSR[FE0,FE1]
-     bits in a thread's context when it receives a signal via
-     pthread_kill.  We can at least fix it in this case by returning
-     to code which uses a UUO to set the MSR[FE0,FE1] bits, and
-     make the handler for -that- UUO return to the real address that
-     was interrupted via pthread_kill.
-
-     I'm so ashamed.
