well, if the limits are reached, the guest can not create
new processes and/or instantiate more memory ... of course
this might lead to program termination and the fact that
a guest cannot be entered (as the limits are hard limits).
raising them will make it all work again ...
in the future we will add soft limits and guarantees too
so that the 'hard' limit can be seen as last resort (and
to prevent DoS)
