IIRC this is intrinsic to the way GHC modifies and garbage-collects array modifications. There's been discussion on -cafe about it. -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH
