Time-HiRes 1.9735 hangs testing

I've just reverted

    Update Time-HiRes to CPAN version 1.9735

because it appears to be hanging testing. Doing a harness -j 16
hung twice with consistently these 3 particular tests hanging:

    ./perl harness
      ./perl -I.. -MTestInit=U1 ../lib/B/Deparse-core.t
      ../../t/perl -I../.. -MTestInit=U2T t/io_utf8.t
      [perl] <defunct>
      [perl] <defunct>
      ../../t/perl -I../.. -MTestInit=U2T t/grok.t
      [perl] <defunct>
      [perl] <defunct>
      [perl] <defunct>
      [perl] <defunct>
      [perl] <defunct>
      [perl] <defunct>
      [perl] <defunct>
      [perl] <defunct>
      [perl] <defunct>
      [perl] <defunct>
      [perl] <defunct>

a trace on the test scripts showed they were waiting trying to write
"ok ...." to a pipe, while the harness process was waiting in select.

I haven't looked any closer, but just reverted the Time-HiRes upgrade for
now.
