Are there other commands that will estimate the current space required for a successful run of "gcore"?

Neither "gcore" command or gcore/generate-core-file command in GDB provide any option to get such an estimate.

Has there been a request to get this kind of information from "gcore" as a future enhancement, since it can be difficult to know just how much space a large running process actually needs.
