Compiling a kernel, having updatedb and mandb run in the background
and then trying to suspend while the compile still runs might do as well.
And this can happen, think of "battery-critical => suspend" setup.
This is exactly the case i do not like the suspend to fail, because there
might not be enough juice left to do a second try.
