Because it was working poorly -- over 50% of the (combined) CPU time was spent
in the kernel ("sys") instead of on compressing the data ("user").
Polling seems to promise relief exactly for such situations, so I tried to
enable it.

Nothing -- the screen (console) is not updated. If I leave top(1) running,
I'll see INSANE amounts of CPU-time (1300% each, for example) getting
attributed to the compressing programs -- after that top stops refreshing.
Hitting a key (even Shift) on the console's keyboard wakes everything up for
some time, and traffic resumes -- only to stall again a minute or so later...
