<span style="font-family:"Calibri","sans-serif""> This program also doesn't behave as expected, native, nothing to do with wow64.
<br>
Anyone else please confirm: <br>
1) my expectations -- it should never print anything<br>
2) their importance -- garbage collector depends on it <br>
3) their not being met -- stuff gets printed <br>
This is in the CVS repository, scratch/wow64stack/sync2.cpp <br>
I am following up further. <br>
Maybe we should get cooperative suspend really going? <br>
Thank you.<br>
