[lldb-dev] Attaching to a stopped (cored) process hangs lldb-server

The problem becomes when the core data on stdin is gigabytes in size and there is little to no diskspace or memory (as the process is still around) to store/process the data.

The process is still around. The process is being handed the core file via STDIN, but the process is still around and this tool is attaching to that process and ignoring the core file data. I would vote to use the core file data if the tool is checked in, or at least provide an option to either attach to the process or use the core file data...
