Comment(by simonpj):
Wait... you say "this exception has become the value of a thunk". Are you
saying that if a thunk evaluation is interrupted by an asynch exn `e`,
then the value of the thunk becomes `throw e`? Surely we should rather
just freeze evaluation of the thunk so if it is evaluated again we simply
resume?
I don't think an asynch exn should ''ever'' become the value of a thunk.
That makes no sense!
