zend_ts_hash_clean not thread-safe?

Hi all.

It seems that zend_ts_hash_clean is not actually thread-safe: it
delegates to zend_hash_clean without first acquiring the write lock on
the hashtable.

Is this behavior an oversight (if so, should I open a bug report with
the trivial patch below?) or is this intentional?
