Roel, Wow, I can't believe we've let this one go unnoticed for such a long time. Of course we should disable pid-watcher for slptool registrations.

Dear devels, Does anyone have any objection to the patch below which disables the 'PID watcher' functionality for services registered with slptool? In my opinion, the slptool register function is quite useless without this, since any registration will automatically be unregistered after a few seconds. On the other hand, with this patch slptool doesn't conform to the properties set in the configuration file anymore, which may be confusing, and which is why I'd like to hear your opinion on this.
