[Haskell] Foreign.Marshal.Alloc questions

[Chris Kuklewicz]

For the allocation functions in Foreign.Marshall.Alloc, are the function 
contracts that return new pointers such that the pointers are never nullPtr, or 
is it prudent to always check the new ptr?

I can see on GHC than allocaBytes uses newPinnedByteArray# but I have not 
tracked down the source file for that to read it.
