    thread.c (do_select): fix leak on exception

    When do_select is interrupted and raise happens from
    RUBY_VM_CHECK_INTS_BLOCKING, the original FD sets we copied
    do not get freed, leading to a memory leak.  Wrap up all the
    FD sets into a Ruby object to ensure the GC can release an
    allocations made for rb_fdset_t.

    This leak existed since Ruby 2.0.0 (r36430)

    [Bug #14929]

    increase timeout seconds.
    * test/ruby/test_io.rb (test_select_leak): increase timeout seconds
      to pass this test on a high-load machine.


    60 sec is not enough at all
