With a Python 3 build on OS X, I get a sporadic failure in
numerical/linear_tensor_element.pyx — it fails not every time, but at least
half the time. As far as I can tell, this is due to #27587 (that is, I get
failures with 8.9.beta8 + that ticket, but not with 8.9.beta8), but I don't
understand why.
$ ./sage -t src/sage/numerical/linear_tensor_element.pyx
too many failed tests, not using stored timings

Unhandled SIGABRT: An abort() occurred.
This probably occurred because a *compiled* module has a bug
in it and is not properly wrapped with sig_on(), sig_off().
Python will now terminate.
