  New Revision: 64524

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=64524

  Log:
    thread_pthread.c (ubf_timer_destroy): remove redundant getpid check
    
    TIMER_THREAD_CREATED_P already checks that pid, and glibc 2.25+
    no longer caches getpid(2).

    trunk/thread_pthread.c
