Just to help things along, I just ran a simple test...  
1. I've confirmed that the problem has been triggered.
2. I shutdown all problems (except window manager and did not restart X).
3. I fired up Chrome to compose this comment.
4. I fired up two accounts.
5. I verified that both accounts are responding normally.
6. Using a second computer SSH'd into this computer, I took an strace sample of
the first wine account.
    Here's the strace command I ran:
       strace -f -p 14714 -c & sleep 5; kill %1
    Here's the strace output:

7. I pointed and clicked several times between the two accounts to get WINE/EVE
to "freeze".
8. I ran a second trace using the same command on the first wine instance. 
Here's the strace output for that trace:

9. I clicked back on the Chrome window to "unfreeze" both wine instances.

Notice that I did not press Alt+TAB once during the whole sequence.

It appears that when the wine instances are "frozen", there is a massive
increase of sched_yield calls, a massive decrease of gettimeofday calls, and no
restart_syscall calls present.

Thanks,
Dyweni
