Take a look at: svn cat http://llvm.org/svn/llvm-project/lldb/trunk/examples/python/process_events.py This tells you how to handle events correctly. The problem with your approach is you won't be able to interrupt a running process because you will be stuck in process.Continue(), so you really do need to switch over to using an event loop as the python above will show you exactly how to do it.
