  Log:
    test/fiddle/test_function.rb (test_nogvl_poll): stop timer hack
    
    EINTR seems unavoidable in real programs (or MJIT), so maybe
    it's not worth dealing with.  r64353 relies on POSIX timers
    to signal.
    
    Switching pipes and sockets to non-blocking by default would let
    us get rid of POSIX timers, timer pthread and this hack:
    https://bugs.ruby-lang.org/issues/14968
    
    [ruby-core:88360] [Misc #14937]
