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
Diffstat (limited to 'libopie/odevice.cpp') (more/less context) (ignore whitespace changes)
