Comment (by George):

 Given the difficulty of fixing compiler bugs of excessive memory use, does
 it make sense to introduce a test to prevent future regressions:

 bash -c 'ulimit -v <appropriate limti for current HEAD.; cabal test'

 We could then change the limit as bugs get fixed or improvements as made.
 This assumes that this test would catch a lot of such errors. If people
 think this isn't the case then maybe such a test would not be worthwhile.
