 I was recently trying to start up with a large initial stack in a Haskell
 program so that I could give a large stack to some foreign code I was
 calling. Unfortunately, no matter what I did with the -K -ki and -kc RTS
 options, the stack size never seemed to change.

 I suspect the problem can be traced to the the following comment in
 source:rts/RtsMain.c

 `/* ToDo: want to start with a larger stack size */`

 It looks to me like the main thread is started without attempting to
 adjust its stack size based on the RTS flags. Is that correct? If so, how
 hard is it to fix?
