The Jenkins stress tests detected memory leaks. For example:
Direct leak of 1060 byte(s) in 53 object(s) allocated from:
#0 0x4a5ce0 in calloc (/mnt/fast/jenkins/workspace/wiredtiger-test-format-stress-sanitizer/build_posix/test/format/t+0x4a5ce0)

It is likely that this leak was introduced by the recent changes to scrub dirty pages. Doesn't reproduce quickly.
