you don't need to fork in order to do wreak havoc.
how do you make sure you know which processes (i.e. which executables)
deserve rt rights? hash them?
and whatever you do, the moment the user loads a user-defined plugin
from a user-controlled location (such as a privately installed LADSPA
plugin), you are utterly hosed.

or am i missing something fundamental here? in which case please
enlighten me.

btw, i'm not quite sure what RTLIMIT_RTTIME is supposed to do. you
define a maximum amount of time that can be spent in rt mode, per user?
or per process? or per group?
if per user, how is scheduling fairness accomplished? does the first rt
process grab as much as it wants, and then another rt process gets
demoted by rtkit because the user used up their rt slice?
