  Log:
    thread.c: fix rdoc
    
    * thread.c (rb_thread_blocking_region): fix typo and the description
      in "Safe C API".  ruby_xmalloc(), ruby_xrealloc() never try acquire
      GVL automatically unless GC runs, but had race condtions without GVL
      acquired until r36284.

  Modified files:
    trunk/thread.c
