devel-warn: issue a warning when writing bookmarks without holding the wlock
I saw an issue in an extension that we develop where we were writing bookmarks
without holding the wlock. Another extension was taking a lock at the same time
and wiped out the bookmarks we were about to write. This patch adds a
devel-warning to urge people to fix their invalid code.
