cpython-lru_cache-weakref: Python/thread.c annotate

annotate Python/thread.c @ 1047:6b5a34db21fe legacy-trunk

Added C++ support in thread.h; don't use signals if not strictly necessary, and when they are, use SIGKILL; when compiled with -DDEBUG, only print debug messages when "THREADDEBUG" is set in the environment.
