I just synced with Greg on some context. I think the nature of attachCommands 
will allow people do anything. What if they have a waitFor command that will 
not get timed out by GDBRemote timeout? Then lldb-dap will never return 
anything to the client. The `dap.WaitForProcessToStop(timeout_seconds);` will 
guarantee we at least return error if things aren't working.

In fact maybe we should consider making the normal launch/attach in async and 
have the `dap.WaitForProcessToStop(timeout_seconds);` at the end to ensure the 
process is in expected state before responding to the launch/attach req?
