            Bug ID: 16577
           Summary: lldb doesn't display inferior thread names during
                    'thread list'
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: lldb-dev at cs.uiuc.edu

    Classification: Unclassified

When debugging an inferior, it can be useful to know the inferior thread names.

For example, when debugging lldb with gdb, we get this:

When debugging lldb with lldb, we get this:
