The exception mechanism is a copy of the OS X "fragile" exception mechanism
using setjmp and longjmp. As such it is wise to only use it as an
exceptional flow control mechanism.
void mulle_objc_exception_throw( void *exception);
Throw an an exception through the runtime mechanism. exception is a user
defined void pointer, that is just passed through. This is a convenient
breakpoint as all Objective-C exceptions are vectored through
mulle_objc_exception_throw.
This may be of interest if you are writing a compiler for the runtime.
Will write some more documentation on demand
