- max_proccesses_reach() and maxload_reached() (why no _ behind max?) are called
both way, static and with object reference.
- this is strongly discouraged and should be avoided as its support (in PHP) may
be dropped in future releases.
- used $a = get_app(); to encapsulate code (even when the function does
currently the same, it may be changed later)

Only define functions if they have not been defined before, e.g. in themes. This makes it possible to override parts of a module and still use the other functions.
