This looks like fallout of the 1.14 changes that made Goroutines
preemptively schedulable.
It seems likely that this code hasn't worked before either, just that
the failure cases were masked because less signals got delivered (and
thus had less chance of interrupting system calls).

With Go version 1.14 I get a lot of errors when I run:
go test -v github.com/pebbe/zmq4 <http://github.com/pebbe/zmq4>
I didn't see this with Go 1.13.8 or any earlier version.
Is this a problem with Go 1.14, or am I doing something wrong and
just got lucky until now?
How do I debug this? The errors are different for each run. Below
is a sample of some errors.
Line numbers are not always accurate, because I inserted some
calls to test.Log().
