  It seems these can be even more abstracted, can I suggested that the
final change uses APR_LOCK_ANONYMOUS_DEFAULT for forked and 
other non-shared applications, and APR_LOCK_NAMED_DEFAULT 
for those applications which much attach to another processes' lock?

  _proc_create and _fork seem to imply they are more specialized than
they really are, but as your STATUS entry pointed out, they require
different mechanics.

  Of course anonymous may be implemented as a named lock on those
platforms which require a name, but apr should (already?) also generate
a random name for such locks on the platforms which don't prefer to
use any unnamed locking method.

  With this slightly more abstract convention, totally +1 to your patch.
