Pushed.
I've added a follow up patch that removes the alarm() timeout code in
the child and does a few more fixes.
The timeout should better be handled, if handled at all, in the
checkpoint code. I would not care much about this case because when the
parent is dead does not talk to the child the test will fail anyway...
