Haven't looked at the proposal in any detail yet, but keep in 
mind that rt.deh2 is only used by DMD. GDC and LDC use GCC's 
libunwind for exception handling on most platforms.

If the semantics of a feature are reasonable, it's probably 
possible to implement it on top of libunwind as well, but it's 
definitely something to keep in mind.
