[Openmp-dev] Status of detached tasks in Clang

[Johannes Doerfert via Openmp-dev]

Hi Joseph,


I'm not sure who is working on this but we might be able to figure this 
out on our bi-weekly call Wednesday.

Feel free to call but we should figure this out either way.


Apologies for the delay,

   Johannes
