I can see the same thing when TTM is off on my 965 box, 
but when TTM is on it will crash X instead of hang when window number > 25
Comment 4 Michael Fu 2008-01-01 23:22:01 UTC 
ttm and non-ttm should be different bugs. please split non-ttm case as a new bug. thanks. we track ttm case here.
Comment 5 Zou Nan hai 2008-01-02 00:35:39 UTC 
is the hang reproducable on 32 bit system?
Comment 6 Colin.Joe 2008-01-02 01:27:46 UTC 
this bug only happens  on 64bit system
Comment 7 Colin.Joe 2008-01-15 19:02:52 UTC 
now ,if you run ./manywin 10 ,it won't hang system now ,but it only draw the last window .that is to say ,the first 9 windows have nothing be draw .
Comment 8 Zou Nan hai 2008-01-15 19:07:28 UTC 
Yes, I can also see this, however it is another bug.
Comment 9 Gordon Jin 2008-01-17 00:13:38 UTC 
So this bug has been fixed.
