Yes, it's 1024.

18000 was for all the wine processes added together. Normally when I run
wine, i see in the process list "wine whatever.exe" and "wineserver".
With this app, I see lots of "wine whatever.exe" processes, so I just
took the sum of them.

I was discussing this with Mike McCormack last night on IRC. He gave me
some ideas and sent me a couple of patches. As I'm not getting very far
with this OLE deadlock, I think I'll look at these patches next.

thanks -mike
