My concern is promoting the httpd 2.3 API to module authors.  They are concerned
that 2.2 users are their audience, plus perhaps 2.0 users, and 2.4 users in the
not-too-distant future.

This makes porting to new 2.4 features less attractive.  mod_mutex seeks to
minimize this downside for module developers.  Doing so for

If your interest is allowing 'Mutex' control of existing 2.2 core mutexes, may
I suggest we still deal with the external use of the 'Mutex' directive as a
module component, since the alternative is that 2.2.16 users could take
advantage of it, but it would conflict with 2.2.15 users installing this
support as a component.
