Hi Michael,

Other pairs of C and Lisp files share the same name without confusion,
so the confusing bit is the feature `threads' that thread.c provides.

That made me wonder why thread.c needs to provide `threads', so I looked
at the history of that file and found that you were the one who added it
(3744fda5fa), apparently in order to be able to skip tests if Emacs is
built --without-threads.

It seems to me that (bound-and-true-p main-thread) would work as a
substitute for (featurep 'threads) in the skip-unless forms in the
thread tests.  Can you think of a reason why it wouldn't?
