1) Fixes for suspend/resume (improved it for iPAQ, shouldn't have changed
anything for Z) -- It seems that this also fixes the 70% CPU load
problem (needs more testing/feedback though)
2) the launcher now creates a /var/run/opie.pid file containing its pid
3) the launcher catches SIGTERM and kills all its child processes
