{- Note [The need for getIoManagerFlag]
   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

   GHC supports both the new WINIO manager
   as well as the old MIO one. In order to
   decide which code path to take we often
   have to inspect what the user selected at
   RTS startup.

   We could use getMiscFlags but then we end up with core containing
   reads for all MiscFlags. These won't be eliminated at the core level
   even if it's obvious we will only look at the ioManager part of the
   ADT.

   We could add a INLINE pragma, but that just means whatever we inline
   into is likely to be inlined. So rather than adding a dozen pragmas
   we expose a lean way to query this particular flag. It's not satisfying
   but it works well enough and allows these checks to be inlined nicely.
