Comment:

 Forgot to close this; tested as fixed in the GHC 7.10 branch:

 {{{
 $ ../../inplace/bin/ghc-stage2 -Rghc-timing -O -c ParserM.hs
 <<ghc: 322519440 bytes, 126 GCs, 5041166/14526288 avg/max bytes residency

 $ ../../inplace/bin/ghc-stage2 -Rghc-timing -O -c Lexer.hs
 <<ghc: 583952016 bytes, 293 GCs, 8581591/22327768 avg/max bytes residency

 elapsed), 0.362 GC (0.362 elapsed) :ghc>>
 }}}

 The `lintAnnots` stuff is taken care of in #10007 like I commented
 earlier.
