<pre>Tested using the svn revision 244212 (3.8.0).
Everything works fine in lldb's CLI. The issue is only with the Python API.
After getting connected, the process is left in "unloaded" state.
The same thing happened with the stable 3.6.2 release too.
=== server output ===
$ lldb-server g :1234 target/debug/des
using the default platform: host
Launched 'target/debug/des' as process 22203...

localhost...
Connection established.
