I'm getting intermittent timeouts from src/sage/doctest/external.py, and in particular the "has_mathematica()" test. This is a new (but underpowered) computer and it does not have mathematica installed. If I run
$ sage --sh $ math-readline then 19 out of 20 times, it fails immediately, but every now and then, maybe when the computer is more heavily loaded, it does something else: it says /bin/sh: math: command not found (as with the immediate failures) and then it waits for input. This must be what is causing the timeout in the doctest. If I hit RET, I get the shell prompt back. Why is it waiting for input when the "math" process failed? Any suggestions for how I could diagnose what's going on?
