We managed to track this down to a fork bug in some Ruby
versions:

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=876377

It is now fixed in Debian stretch/stable but other distros
might still have this problem.

Tried that, it doesn't seem to do anything but prefix the lines with the pid:

[pid 24923] sched_yield()   = 0
[pid 24923] sched_yield()   = 0
[pid 24923] sched_yield()   = 0
