Good idea, the first strace shows that SIGALRM was received while
Python was creating the large data.

I made this simple change. Can you tell me if my change fixes the issue?

It may make the test more reliable and I don't see how it can fix the
issue showed in the strace. Feel free to make the test more reliable
with such change if you want.
