Jon, you mentioned that all exceptions should be caught within the API.
If we do this... will that save us from the linkage problems?
If so, I think we should pursue this for 0.9

Personally, I run my apps outside an IDE, also, I don't use gdb much,
so having exceptions would help me trace denormals without having me
to put breakpts in gdb runs.
