Considering the fact that its probably unreasonable to ask the user
code to catch the VME everywhere, or that VME may not even reach the user
code,
should we have something like -XX:DieOnVME=<process_error_code> ?
 Or global VM VME handler that has certain amount of pre-reserved memory,
which gets executed before VM terminates, and can be configured?

Thanks,
