OK, this is correct.

I have proposed apr just to avoid yet another reimplementation of
dynamic arrays. This would maybe save time and apr seems to be good
for other things too, like you have suggested. I don't think I need to
write another rfc, we could all agree on using apr for dynamic arrays
as that is the subject of rfc17 and then write other rfcs for
re-engineering other bits of mapserver to use the APR apis.

<dreaming>
We could even make mapserver an apache module and get a super fast
mapserver interface.
</dreamin>

Just my 2 cents,
Umberto
