When you cut & paste the PR form, please don't lose the returns - it's
impossible to read.

First off, it's only a warning - and the ntop code, by detecting that you
already have the lock and skipping the pthread_mutex_lock() call avoids the
potential for a deadlock.

Secondly, as I've posted before, we track the locking via add-on data to the
actual mutex.  Because this data isn't part of the actual mutex, there is a
slight window where we could lose an update and thus report out-dated or
eroneous information.

The cases where it's a concern are when it happens frequently.  A single or
rare occurance is nothing to worry about.
