test/ruby/test_io.rb (test_select_leak): speedup and reduce memory use
We can reuse the sub-thread and exception with Thread#raise to
reproduce the old memory leak with less overhead. This allows
us to to run more iterations and improve reliability of the
actual test, particularly on platforms without USE_THREAD_CACHE.
For glibc and jemalloc, also limit arena count to avoid
inadvertant growth.
