* rubysig.h (CHECK_INTS): prevent signal handler to run during

critical section.  [ruby-core:04039]

* eval.c (load_wait): need not to call rb_thread_schedule()
  explicitly.  [ruby-core:04039]

* eval.c (rb_thread_schedule): clear rb_thread_critical.
  [ruby-core:04039]

* st.c (st_free_table): do not call free() but xfree().
