It runs just fine, but ignores signals such as SIGINT, so you can't quit
without kill -9.
The same versions of copyparty and python work as expected on FreeBSD 14.3
and OpenBSD 7.8, so there's something a bit funky about NetBSD's signal
handling here.
Hmm. In FreeBSD, OpenBSD & Linux, pthread_sigmask(3) seems to apply
per-thread,
but on NetBSD, the whole process gets blocked--not just the thread which
called
pthread_sigmask():
In case it's a clue, I found that the signal isn't entirely ignored, but
it takes 10 minutes to take effect:
