I'm seeing a bunch of systems start failing with this release, they
start OOMing when previously they ran OK.  Most of them aren't exactly
overburned with memory.  These failures bisect to 61717acddadf66

bisect from one of the systems including links to test jobs (the bisects
for other systems/test sets look very similar):
