Pardon my late...
Somewhere in the thread someone asked what's slow? To help
decide what belongs in/out I just happen to have some profiler(CPROF
http://opensource.corel.com/cprof.htm ) output lying around
so its *share time*.
Here is what the wineserver is doing during quick run of Presentations:

[snip]
1) server_call_noerr() - wineserver - is always 91-95% of the app side.
(The kernel module/syscall looks to address this problem. Yay!)
/* calls 2,3,5 form 3 chains that fill out the top ten */
2) TryEnterCriticalSection
calls - #8 InterlockedDecrement
#9 GetCurrentThreadID
#13 InterlockedCompareExchange
3) CRITSECTION_EnterCriticalSection()
calls - #6 EnterCriticalSection
#11 GetCurrentProcessId
4) __get_teb() is pure assembly
5) CRITSECTION_LeaveCriticalSection()
calls - #7 LeaveCriticalSection
(note: __get_teb and the InterelockedFOO functions are not inlined in
the
Corel tree.)
I hope this is *on topic* and usefull ( else > /dev/null ).
