That should improve the situation. However, depending on which syscalls one uses, process may still seem "stuck" after restart because the current code still does not save signals nor task timers; If a signal was pending (SIGALRM for example) after freezing but before checkpoint, it will be lost. If a timer was set at checkpoint, it will not be restored. So depending on your program, you may still experience issues until I add patches to handle that. Oren.
