[hepsrc] dvegas-1.1alpha1 bug fix

[Nikolas K. <nk...@us...>]

The change

- loop_worker() no longer public

broke the code.  loop_worker() cannot be made private 
since it is returned in loop_worker_wrapper() with C 
linkage to the pthreads library.

You can find the corrected version, with loop_worker() 
moved from private to public, at the usual place:
