I recently proposed using nothrow in GtkD as well. This

with binding to C code unfortunately. Especially on amd64 with
GCC compiled stuff since it omits the stack frame that DMD
requires to unwind the stack resulting in immediate crashes
(druntime HLTs the execution) as soon as you throw an
exception from a callback.
I agree that C callbacks called from C code should be nothrow.
At a minimum, the C code that calls the callback is not going to be expecting an
exit via exception, and so may leave things in an indeterminate state.
