Would you prefer something like the following example?

>>> sys.thread_info
sys.threadinfo(name='pthread', 'lock_implementation': 'semaphore',
version: 'NPTL 2.11.2')
>>> sys.thread_info
sys.threadinfo(name='nt', 'lock_implementation': 'semaphore', version:
'')
>>> sys.thread_info
sys.threadinfo(name='os2', 'lock_implementation': '', version: '')
