Strictly speaking, disabling paging will not affect latency switching
between tasks, only the time it takes for the switched-to task to run
(and that, only when it needs a paged-out page promptly).

Past versions behaved rather badly when all RAM+swap was exhausted
(which is significantly easier to do if you have no swap).  I haven't
tried stressing 2.0 in that regard, but it wouldn't surprise me if it
misbehaved too - wedged, or started killing processes "at random", or
some such.
