[Mono-list] mod_mono process list

[Ben Clewett]

OOps, attached image was zero size.  Try this one...

The graph is screen-scraped of the mod_mono control panel on 2.0.1.

Showing how process count builds up until server fails.

My aim: to get mod_mono to list the processes so that I can try and 
trace the problem.

Any help very welcome!

Regards,

Ben
