winedbg backtrace during the busy state

It takes 3-4 minutes until the Map Editor for HoMM V appears when Windows
version is set to Win2000 or higher in winecfg. Using Win9x/Me, or WinNT40/35
profiles, the editor loads up in less than 10 seconds.

Wine doesn't print anything in the terminal until the editor window appears.
There is no hdd activity, but cpu usage is constantly ~100 % while Wine is busy
with loading the editor.

If I attach winedbg to the H5_MapEditor.exe process, I always get the same
backtrace as can be seen in the attachment.

It should be noted that bug #29603 describes a very similar problem. Of course
I have no proof if they're about the same problem, but the similarities are
striking.
