Bug #166: Signal handling and sleep() don't work together

=begin
Setting up a sleep seems to interfere with signal handlers. The following code

trap("CLD") do
pid = Process.wait
puts "Child pid #{pid}: terminated"
end

exec("/bin/sh -c 'echo hello'") if fork.nil?
puts "start"
sleep 2
puts "done"

Outputs start/hello/done with no delay, and the trap never fires. Replace the sleep with a gets, and the signal handler gets invoked—it never writes “Child xxx terminated.”
