 %feature("docstring",
 "Represents a thread of execution. SBProcess contains SBThread(s).

 SBThreads can be referred to by their ID, which maps to the system specific thread
 identifier, or by IndexID.  The ID may or may not be unique depending on whether the
 system reuses its thread identifiers.  The IndexID is a monotonically increasing identifier
 that will always uniquely reference a particular thread, and when that thread goes
 away it will not be reused.

 SBThread supports frame iteration. For example (from test/python_api/
 lldbutil/iter/TestLLDBIterator.py),

         from lldbutil import print_stacktrace
         stopped_due_to_breakpoint = False
         for thread in process:
             if self.TraceOn():
                 print_stacktrace(thread)
             ID = thread.GetThreadID()
             if thread.GetStopReason() == lldb.eStopReasonBreakpoint:
                 stopped_due_to_breakpoint = True
             for frame in thread:
                 self.assertTrue(frame.GetThread().GetThreadID() == ID)
                 if self.TraceOn():
                     print frame
