--- Comment #1 from Mark Johnston <markj at FreeBSD.org> ---
This was recently fixed in head by r360380 and some related revisions.  I tried
your test case:

markj at biggie> python test.py
filling pipe buffer
select() says the write pipe is NOT writable
closing read end of pipe
select() says the write pipe is writable
waiting for kqueue to report the write end is writable
done!
[<select.kevent ident=4 filter=-2 flags=0x8010 fflags=0x0 data=0x0 udata=0x0>]

The fixes will be available in 12.2.
