[PATCH] Add -X back in...
Assuming no one vetoes this, this can get committed before we tag
tomorrow. No rush though. =-)
- Updates upgrading.html
- Reverts Aaron's earlier docco patch (sorry...)
- Adds -X to all mpms in the tree
I won't be around tomorrow morning to commit this before 2.0.26 is
tagged. If it doesn't make it into 2.0.26 and no one has vetoed it,
then I'll commit it on Friday. -- justin

This continues to use the "defines" mechanism, so I'm happy.

Cheers,
-g
(i.e. changing it to the hack that used to be there -- some kind of global
that each MPM had to deal with... that was ooky; this patch looks good)

Don't sweat it, spmt_os2 will be going away soon. mpmt_os2 supercedes it.

Um...ONE_PROCESS and NO_DETACH are not going away, so don't remove that
comment. How about just add something about -X/-DDEBUG providing the same as
ONE_PROCESS and NO_DETACH. This may seem a minute point, but you have to
put yourself in the shoes of someone who is unfamiliar with the code.
Newbies will now read the comment and will not be able to figure out
why -X does what the comment says it does. At least for NO_DETACH I could
just search for that string and I'd find where the logic is.
