/proc/sys/vm/swapout_interval is useless

It is impossible to finetune swapout_interval using
/proc/sys/vm/swapout_interval because any value written to it is
multiplied by HZ, and the only usefull values are smaller than HZ. But
proc interface for sysctl cannot cope with fractional values. The only
chance to change the value of swapout_interval is to use the sysctl
syscall, which uses the raw number.
