This use case is probably also relevant to the PNaCl people - if the output of the JIT violates the SFI requirements of their sandboxing platform (possible due to a compiler bug) then they need to be able to abort.  I think that they’re currently not lazily JITing, but given how important startup times are to them this is probably not ideal.
