Which was uncovered by the Jenkins valgrind test (http://build.wiredtiger.com:8080/job/wiredtiger-valgrind/2014/)
The stack trace is:

The problem is that doing an assertion is calling fsync on stderr, which is asserting that it's not doing an fsync when running read only.
The check for fsync in a readonly connection should not be applied to standard I/O calls.
