  Log:
  Install a SIGCHLD handler so select(2) will be interrupted when a child
  terminates.  Without this patch, 'make -j1 buildworld' takes about 30%
  longer than 'make -B buildworld' on my 2.4 GHz P4; the difference is
  probably even larger on faster systems.  With this patch, there is no
  perceptible difference in wall time between the two.
