That's not a nasty hack, that's the right way to do it.
Your system should keep track of the servers it's started, and when they
last had requests run on them, and kill servers when they're no longer
required. From the sounds of things, you don't even need a concept of a
server being associated with a particular session - you can just regard them
as a pool of displays for doing the "capture" process on, and remove &
restore them from/to the pool before & after processing a request, and add &
remove servers as the pool becomes empty, or idle for prolonged periods,
respectively.

Well, it is bit nasty.. or inconvenient at least in the context from
which this is being run, i.e. asynchronous requests from a web server.
You could say I'm being lazy and I suppose you'd be right. I'll have to
a create an Xvnc activity/logging/cleanup daemon to handle all this,
which is a drag (I don't have root access, nor cron, and I'll have to
move all this to other servers). Either that or I call all the
maintenance tasks with each users image request, which sounds like it
could get heavy (race conditions etc). The pool of servers idea sounds
nice and I had thought of something like that to try to maintain say 20
servers running at any one time. However how can I know which one in the
pool isn't busy and hasn't just been bagged by another user? ah, I see,
I'll have to manage that too.
All this would be *so* much easier if I could just launch an Xvnc
server for each user session that quietly went away after n minutes of
inactivity. Oh well, never mind. Thanks anyway.
