New description:

 Cilk Plus is a C++ language extension developed by Intel.  It is proposed
 as a C++ standard extension. It uses a work stealing scheduler.  Similar
 to OpenMP it consists of two parts,

 * the code generation by the compiler, and
 * a run-time library.

 The code generation works for the RTEMS using a recent GCC.  It is
 feasible to port the run-time library (libcilkrt) to RTEMS.  However, some
 issues must be dealt with.

 * Currently virtual memory via `mmap()` is used to manage the worker
 stacks (cactus-stack).
 * This could be changed to use a pool allocator.
 * What happens in case of stack overflows, e.g. no protection pages?
