threadDelay appears to use excessive CPU in GHCi

|Test Case:||Blocked By:|
I have the following simple program:
main = threadDelay (106) >> main
If I run it in GHCi it requires 2-5% of my CPU. If i compile it, it
takes 0% of my CPU. It does not matter if I compile -O0, -O2,
-threaded, it always uses 0% (which is good).
I have only tested this under Linux (Ubuntu Hardy) and GHC 6.8.3 on one machine.
