Patch #8594 http://www.winehq.
com/hypermail/wine-cvs/2003/06/0232.html causes problems with 
Hamster v2.0.0.1 (downloadable from http://www.tglsoft.
de/misc/hamster_en.htm), a local mail and news server.

When Hamster connects to a remote server and tries to read data, 
it immediately loses the connection with an error.  After some 
debugging on my own, it seems that WS_select is noticing data 
available for reading on the socket, but then ReadFile returns 0 
bytes and STATUS_SUCCESS.

Reversing patch #8594 fixes the problem.  Other networking apps 
seem to work fine, so I suspect the problem is specific to 
overlapped I/O on sockets.

A section of +file,+winsock logging before the patch

trace:winsock:__ws_select read 0x42592318, write (nil), excp 
(nil) timeout 0x42592310
trace:winsock:fd_set_export 
trace:file:ReadFile 0x70 0x41817388 1024 0x4259240c 0x425923f8
trace:file:FILE_ReadFileEx file 0x70 to buf 0x41817388 num 1024 
0x425923f8 func (nil)

trace:file:GetOverlappedResult waiting on 0x425923f8
trace:file:FILE_AsyncReadService 0x425923f8 0x41817388
trace:file:FILE_AsyncReadService read 59 more bytes 59/1024 so 
far
trace:file:GetOverlappedResult wait on 0x425923f8 returned 192
trace:file:GetOverlappedResult waiting on 0x425923f8
trace:file:GetOverlappedResult wait on 0x425923f8 returned 0
trace:file:GetOverlappedResult (0x70 0x425923f8 0x4259240c 0)

After the patch, there's just

trace:winsock:__ws_select read 0x42592318, write (nil), excp 
(nil) timeout 0x42592310
trace:winsock:fd_set_export 
trace:file:ReadFile 0x80 0x41817324 1024 0x4259240c 0x425923f8
trace:file:GetOverlappedResult (0x80 0x425923f8 0x4259240c 0)
