[lldb-dev] Threading model for Python API

[Greg Clayton via lldb-dev]

The API is thread safe, but you can run into interesting issues if you don't thread things right. You don't want one thread stepping and another thread resuming. It will work, but you probably will have a tough time figuring out why certain functions return certain values. Also, you don't want one thread resuming a process while another things the process is stopped and tries to get and display local variables.

So yes the API is thread safe, but be careful with how you use things.
