While looking at https://github.com/llvm/llvm-project/issues/61955 I noticed that when we send qLaunchGDBServer we check that we got a response but not what kind of response it was. I think this was why the bug reporter saw: (lldb) run error: invalid host:port specification: '[192.168.64.2]' The missing port is because we went down a path we only should have chosen if the operation succeeded. Since we didn't check, we went ahead with an empty port number. To test this I've done the following: * Make a temporary copy of lldb-server. * Run that as a platform. * Remove the copy. * Attempt to create and run a target. This fails because the running lldb-server will try to invoke itself and it no longer exists. Reviewed By: jasonmolenda Differential Revision: https://reviews.llvm.org/D153513

from Python because we can juggle multiple processes more easily.
