* generic/tclThreadTest.c (ThreadEventProc): Corrected subtle
bug where the returned (char *) from Tcl_GetStringResult(interp)
continued to be used without copying or refcounting, while
activity on the interp continued. That's not safe, and recent
changes demonstrated the lack of safety with failing tests
thread-4.3 and thread-4.5.
