I've pushed patch adding a slightly incorrectly named:

manageSpawnWithGC :: ([(ProcessID, ManageHook)] -> X [(ProcessID,  
ManageHook)]) -> ManageHook

Some options for the first argument are:

f1 = return -- never delete anything old

f2 = return . take 100 -- keep 100

f3 xs = do -- keep roughly the number of processes you have
   ps <- readProcess "ps" ["u"] ""
   return (take (length (lines ps)) xs)
