Research direction
Review the existing ELF and MACH0 coredump generation and loading code in the radare2 codebase, particularly in the core and binary analysis modules. Check the referenced issue #152 for background on initial requirements. Read through the 48 comments on this issue to understand any obstacles or prior attempts. Determine what remains for BSD ELF coredump generation and mach0 thread support.
