No, I think you are right. However the whole
signal/eval/die/setjmp/longjmp mess is pretty much broken anyway, what
with the non-MT safeness and the current bizzare behaviour illustrated
by Raphaels test script.
I'm still intending to disable sigsetjmp - I havn't heard any decent
reason for it being used.
