 ahh, then... not being funny or anything, but this might be a
problem.  bug-for-bug compatibility would imply having to bring that
limit down to match what nt does. ... actually.... is there a second
location where there are handle / filedescriptor limits? the reports i
read seemed to indicate that there was a filedescriptor limit of 2048
and a handle limit that was far in excess of that (just like wine)

 i'm not, and neither is the application - that's the point.

 ... but on windows, the application _is_ hitting the limit (of 2048)
and is gracefully throwing errors.
