That's a huge area. One avenue of attack is to have
a way in superserver to identify a piggish thread and
kill it. There are many more, most of which need to be
verified with performance measurement.

What have you done to identify the source of the
problem? Even without changes to the server, there
should be ways to improve performance. I/O bound?
CPU? Memory? Do you allow ad hoc queries?...
