[lldb-dev] Multiple targets/processes

[Greg Clayton]

To further clarify: no stdio for a process means the ProcessIOHandler doesn't get pushed and it stop it from trying to take over the terminal and allows commands to be run on the command line while the process is running.

If an IDE was running this, it might create a new SBDebugger, one for each debug window. When the IDE launches a process, it would redirect the STDIO to the slave side of a PTY while the IDE would have the master side open allowing it to communicate with the process on a side channel (stdio window). So you are running into this problem because you are trying to do this with the command line LLDB and IO is enabled.
