It looks like it is.

I'm not that familiar with the code that manages breakpoints, but it
seems that they are applied to a tree_statement_list object, so they
would only apply to a single function body.  I don't see that there is
any global list of breakpoints.  I'm also not sure that this is the
best data structure for managing breakpoints, so it may change in the
