Comment (by Olly Betts):

 I worked out the problem on NetBSD - it's that `SIGEV_THREAD` is not
 implemented (still true in NetBSD 9.2).  This information is near the top
 of `man sigevent`.

 I tried a pthread-based implementation, which works on Linux at least.  I
 wonder if using standard C++ thread functionality would be simpler (we'd
 avoid having to mess with probing for pthreads stuff, which looks a bit of
 a mess from https://www.gnu.org/software/autoconf-archive/ax_pthread.html
 - some platforms require a different compiler even!)  It would also give
 us support for non-pthreads platforms (__WIN32__ being the main one).  The
 downside is I think we need `std::jthread` which was added in C++20,
 rather than `std::thread` which is C++11.
