Starting a windows exe with wine is slow, because the wine should be initialized first which is slow (mapping and linking a lot of dlls, analyzing config files, mapping resources, etc).
I think if wine could run like a daemon which could give its context to a newly started exe, it could significantly fasten the exe startup time. Although transfering some resources (file descriptors, mappings) between processes isn't easy and isn't always posix-standard, in newer Linux kernels it is already possible.
As I know, there is a wineserver in the wine, but unfortunately I didn't find too much from it in the Google.
Does some similar already exist? Or can it be done with the current wineserver, too?
