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.
