--- Comment #33 from Luke Kenneth Casson Leighton lkcl@lkcl.net 2011-03-27 18:53:59 CDT --- it's free software, you don't need my permission :)
you do, however, need to take into account the fact that this is a severely resource-hungry non-optimised solution which can in no way be put into a production environment.
to properly solve this issue, i'm afraid that wine is going to need a quite significant architectural "upgrade": wineserver must become multi-threaded.
this would also solve other quite serious and subtle bugs/issues including a long-standing performance issue (in certain circumstances) across a broad range of win32 applications.
