We need (Linux terminology is used in this ticket) a way to dump core that does not include the memory mapped files. This will become more critical as we move to better (and therefore complicated) algorithms where examining memory will yield information we cannot otherwise access and speed up the diagnostic process.
Having a core dump is the only way to have a historical record of a process state.
Currently this isn't possible as all signals are caught.
Having this internal to mongo such that development programs aren't installed would be ideal.
