  New Revision: 64357

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=64357

  Log:
    thread_pthread.c: use UBF_TIMER_PTHREAD on Solaris
    
    I'm not sure what's causing this failure in Solaris and only
    on rubyspec, since rb_io_wait_readable is a well-exercised
    code path in other places.  But maybe using a pthread for
    timing (similar to old timer-thread) can solve the issue.
