Bug#460230: Patch to use nanosleep()

[Philippe Teuwen]

Package: lkl
Version: 0.1.1-1
Followup-For: Bug #460230

Hi,

I encountered the same problem.
It looks like lkl was polling every microsecond 
while every millisecond is largely enough.
So here is a patch, I also moved from usleep() to 
the more POSIX compliant nanosleep().
