Is there some (easy) way to avoid this while still using readFile?

readFile' f = do s <- readFile f return (length s `seq` s)

(and curse the fact that the default readFile is unsafelazy).

:( Doesn't work. I'm starting to suspect there is no automatic close of opened files even after they've been completely read.

I'd also suggest using strict io here, either vi: readFile' f = do s <- readFile f length s `seq` return s -- n.b Jules :) or Data.ByteString.readFile -- Don
