George Russell:

If I run GHCi but leave it doing nothing and waiting for input, the process nevertheless eats CPU time, and is at the moment bringing my RealAudio relay of Gardeners' Question Time to a halt. Do the GHC Team have anything to suggest for dealing with this problem?

Doubtless due to some _fiendishly_ clever static analysis going on in the background? And let's face it, GQT (and arguably R4 in general) is definitely "background". ;-) Cheers, Alex.
