The issue here is that a browser may open a connection to the

actively using it.
 Of course, this isn't specific to VMS, or a function of how VSI
ported it or whatever else Arne initially thought.

What's specific to VMS is that pre-fork MPM is the only game in town if
you want to use Apache.  Whether the other mechanisms in use on other
platforms and designed specifically to address the problem Arne
encountered could be made to work on VMS is an open question, but not
something anyone outside VSI could try without the sources.  I think
event is out because there is no kqueue or epoll.  The worker model
might be possible.  Or a custom one using ASTs instead of pthreads.
