  New Revision: 61598

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=61598

  Log:
    test/ruby/test_io.rb: relax RLIMIT_NPROC for invocation of ruby
    
    This limit seems to be too restrict.  It sometimes produces the
    following warning when running `make test-all`:
    ```
    TestIO#test_close_on_exec<main>: warning: pthread_create failed for
    timer: Resource temporarily unavailable, scheduling broken
    ```
