Sorry for missing this back in August.
I think it'd be clearer to import your python once in the startup, like
-o "script import $module" \
Multiple imports are a no-op IIUC so it's harmless to re-import the module every time the breakpoint is hit (I'm guessing it's only hit once, for that matter), but I think it's clearer to have this on its own line.
For what it's worth, if you use breakpoint command add -F python-function, your function is passed in the frame as well as the SBBreakpointLocation. See 'help breakpoint add' for more information about this; I used this in a breakpoint python command I wrote a while back,
def handle_pthread_create_return(frame, bp_loc, dict):
thread_index_id = frame.GetThread().GetIndexID()
it might be a good idea to name the breakpoint you're adding and then you can delete it explicitly, in case the user is doing something unexpected with breakpoints. e.g.
% ~/k/svn/lldb/build/Debug/lldb /tmp/a.out
(lldb) target create "/tmp/a.out"
Current executable set to '/tmp/a.out' (x86_64).
(lldb) br s -n main -N worker
Breakpoint 1: where = a.out`main, address = 0x0000000100000ec0
(lldb) br del worker
1 breakpoints deleted; 0 breakpoint locations disabled.
(lldb) br li
No breakpoints currently set.
