Lazy require benefits from using a lock on a namespace registry for much the same reason as on-demand instantiation of ready modules. Make lazy require use the lock that's alerady in place for on-demand instantiation, and expose `namespace-call-with-registry-lock` for other potential uses. Thanks to @m4burns for tracking down the problem and its solution. Related to #3805 |
