Currently, HPX on BG/Q is using the posix user level context switching API. It turns out to be slow. We need to find a way to make either Boost.Context work or write our own context switching assembly routines.

Boost.Context will support BG/Q with 1.56. The context switching is already properly implemented in the current boost master branch.
