xargs can be fooled by exiting children that it did not start, causing
it to kick off a new command before the previous has finished, resulting
in corrupted (interleaved) output.  It is also fooled by non-exiting
children it did not start, failing to exit until all extraneous children
have exited.

This patch makes xargs keep track of children it starts, ignoring
pre-existing ones.
