Today I realized that async-io's test was making the Linux salmonella
machines hang.

strace shows that the test process gets stuck on an endless loop running:

  poll([{fd=4, events=POLLIN}], 1, 0)     = 0 (Timeout)

I could reproduce the problem on my system with:

  $ for i in `seq 100`; do csi -s run.scm && echo $i; done

It eventually hangs.

Do you know what could be causing this?

All the best.
