ngoto 5faf4cc77b * ruby_atomic.h (ATOMIC_CAS): added for Solaris and other platforms. 
* ruby_atomic.h, signal.c (NEED_RUBY_ATOMIC_OPS): renamed from
  NEED_RUBY_ATOMIC_EXCHANGE.
* signal.c (ruby_atomic_compare_and_swap): naive, non-atomic
  compare-and-swap implementation only used for platforms without
  valid support for atomic operations.

kosaki 6190bb4d8a * ruby_atomic.h (ATOMIC_CAS): new macro for compare-and-exchange. 
* vm_core.h (struct rb_thread_struct): add interrupt_mask member.
* thread.c (thread_create_core, Init_Thread): initialize
  th->thread_mask.

* vm_core.h (RUBY_VM_INTERRUPTED_ANY): new macro for avoiding
  bare th->interrupt_flag.
* vm_core.h (RUBY_VM_INTERRUPTED, RUBY_VM_INTERRUPTED): check
  th->interrupt_mask.
* thread.c (set_unblock_function, rb_thread_schedule): replace
  th->interrupt_flag with RUBY_VM_INTERRUPTED_ANY()

* signal.c (signal_exec): set up thread->interrupt_mask for
  preventing recursive trap handler.
* vm_core.h (RUBY_VM_CHECK_INTS, RUBY_VM_CHECK_INTS_BLOCKING): ditto.

* thread.c (rb_threadptr_execute_interrupts):
  don't process interrupt if it is masked.

* gc.c, signal.c, vm_core.h, common.mk: reflect the rename from atomic.h
  to ruby_atomic.h.
