Comment(by pcapriotti):

 I run a couple of tests on some code in nofib. There were no significant
 differences, and in one case I actually got better timings after the
 patch.

 Here's one of the tests:

 `nofib/imaginary/test.script`:

 {{{
 :set args 8
 :l ./bernouilli/Main.hs
 main
 :l ./integrate/Main.hs
 main
 :l ./primes/Main.hs
 main
 :l ./queens/Main.hs
 main
 :l ./x2n1/Main.hs
 main
 :l ./paraffins/Main.hs
 main
 :l ./wheel-sieve1/Main.hs
 main
 :l ./tak/Main.hs
 main
 :l ./rfib/Main.hs
 main
 :l ./exp3_8/Main.hs
 main
 :l ./wheel-sieve2/Main.hs
 main
 }}}

 before patch:

 {{{
 real    0m7.058s
 user    0m6.996s
 sys     0m0.036s
 }}}


 after patch:

 {{{
 real    0m6.844s
 user    0m6.808s
 sys     0m0.016s
 }}}
