                    that threads in some applications might look up
                    causing periodical lookups

After `b8ca0eae9f47491ba257c422a2bc03fc37d13c22` that changed
ntdll-NtAlertThreadByThreadId the threads of some applications might lookup up
causing periodical freezes for 1s-3s in some applications like Wotld of
Warcraft or Deus Ex.
The rest of my session still works and does not freeze when that happens.

In the case of Wow I especialy noticed that the input will be open again sooner
than the graphics/sound.


The log will look like this:
02cc:err:sync:RtlpWaitForCriticalSection section <same address> "?" wait timed
out in thread 02cc, blocked by 0000, retrying (60 sec)

I noticed that in the case of Wow the critical section that looks is almost
every time the same.
