[netCDF #GDU-185487]: netCDF support for HDF5's SWMR mode



Hello Jamie, 

We are investigating the possibility of including some of the features in HDF5 
1.10.x, including SWMR, but we do not have a roadmap for including any of these 
features at this point. 

I'm sorry I can't provide a more positive or directly useful answer, but I hope 
this information is useful. 

Have a great day,

-Ward
