#1586: trace output ordering in HEAD incorrectly

--------------------------------+-------------------------------------------
I don't have a test case, but it appears that the Debug.Trace.trace output
is ordered incorrectly. By incorrectly, I mean that it does not follow
evaluation order. I suspect it will come up in every non-trivial use of
it. In GHC-6.6.1 the output order was correct (modulo that the size of
output was not equal during runs (but there is another report for that
already)).
In a program I have
{{{
runFoo $ do
() <- trace "hi" (return ())
() <- trace "there" (return ())
return ()
}}}
prints:
{{{
there
hi
}}}
