-------------------------------------+-------------------------------------
 With the merge of Phab:D169 and Phab:D396 (included in GHC 7.10.1) GHC now
 has the ability to produce DWARF debugging information in compiled
 binaries.

 It would be nice if Haskell programs could request stack backtraces from
 the RTS. Tarrasch has some work in this direction in Phab:D963 however
 there are a number of questions that remain outstanding,

  * do we want to rely on an external library for parsing DWARF
 information? If so, how do we address portability concerns?

  * What should the Haskell-land interfaces look like? Writing down some
 concrete use-cases would help here.
