On my Debian GNU/sid machine, slapd stops serving if any user runs the
following: 

$ renice 19 $$; while [ 1==1 ]; do echo -n ""; done

The result of this command, run by *any* user logged in, is that nobody else can
log in.

A better example is that if a user compiles and runs the following code, nobody
can log in:

int main() { while(1) {} return 0; }
