Comment (by fhgwright):

 I'd started investigating this before noticing the python38 patches, and
 it seems that a one-line patch is sufficient to convince it that native
 thread naming doesn't exist prior to 10.6.  I don't know if anything more
 elaborate than that is really needed.

 Similarly, a one-line patch is sufficient to get rid of the COPYFILE_DATA
 reference, though the consequences of disabling the corresponding Python
 definition (including in shutil and test_shutil) would need to be
 investigated.  I do notice that the "fast copyfile" mechanism isn't
 expected to be available on all OSes, according to the Python docs.

 A recurring problem with 10.4, affecting Python and Ruby at least, is that
 it implements the fcopyfile() ''function'', but not the COPYFILE_DATA
 ''option'' for it.
