* test/thread/test_queue.rb (TestQueue#test_thr_kill): reduce
	  iterations from 2000 to 250. When running on uniprocessor
	  systems, every th.kill needs TIME_QUANTUM_USEC time (i.e.
	  100msec on posix systems). Because, "r.read 1" is 3 steps
	  operations that 1) release GVL 2) read 3) acquire gvl and
	  (1) invoke context switch to main thread. and then, main
	  thread's th.kill resume (1), but not (2). Thus read interrupt
	  need TIME_QUANTUM_USEC. Then maximum iteration is 30sec/100msec
	  = 300.
