[Pywps-devel] Some more fixes & development thoughts

[Panagiotis Skintzos]

Hi,

It's great that you have this; please send it to me, I'm sure it'll be
very useful.

Regarding mod_python & apacahe, I'm sceptical of how the forking would
work (in case of asynchronous processing). Generally it's not a good
idea to fork an Apache process; especially in a production environment.
Maybe using threads would be better approach.
But I'll try all options and see how it goes.

Cheers,
Panagiotis
