I'm confused by Jason's comment as well.

The various x86-win32 targets currently use sjlj EH, and mostly because 
nobody has taken the time to implement dwarf2 unwind based EH.

Before we see talk about disabling sjlj and such, could we get more 
info on (1) how to implement non-sjlj EH for non-ELF, and (2) some docs, 
or pointer to if already existing, to the tables and how these are used.

For pe-coff, we have an added issue that has to do with exceptions
crossing DLL boundary, but that's an issue we can deal with after the
basic support is added.
