  New Revision: 39780

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=39780

  Log:
    test_bignum.rb: refine test
    
    * test/ruby/test_bignum.rb (test_interrupt_during_to_s): rename and
      merge with assert_interrupt, separate Bignum power from to_s, get
      rid of busy loop, and skip if the conversion is too fast.

  Modified files:
    trunk/test/ruby/test_bignum.rb
