  New Revision: 64542


    thread_sync.c: common wakeup_{one,all} implementation
    This let us avoid looping in rb_szqueue_max_set, saves us
    some lines of code and reduces binary size slightly
    (numbers from 32-bit x86):
             text      data     bss     dec     hex filename
    before: 91272       392     156   91820   166ac thread.o
     after: 91200       392     156   91748   16664 thread.o
    Inspiration from this taken from the FUTEX_WAKE op
    of the Linux futex(2) syscall.
