I've never experienced any problems like that.  I suspect it's
probably one of those things that shows up under load.  As my desktop
box spends quite a lot of the time sitting pretty much idle, then
fvcool does it's thing without problems.  If it was a hard working
server then I suspect that a) the sort of problems you mention would
probably show up and b) there wouldn't be that much point running
something like fvcool anyhow, as the CPU would be active much of the
time anyhow.
