When debugging a multithreaded application in CodeGear under Windows XP, users have found that the debugger locks up the Windows kernel frequently (twice a day for me). When the Windows kernel locks up (actually slows to a crawl), if you hit CTRL+SHIFT+ESC to bring up the task manager, it will not come up until after a few minutes. While waiting, hit CTRL+SHIFT+ESC say 50 times. You'll get 50 task managers appearing after the first one pops up.
At this point, Windows XP kernel is still painfully slow - Task Manager shows no CPU usage, kernel's just 99.9% locked up. With that 0.1% responsiveness, you'll be able to slowly terminate bds.exe and again, wait ages for the confirmation window to pop up. Once bds.exe is terminated, your system will be fully responsive again. You'll be left with the above screen shot.
Good job CodeGear, for your ability to bring XP kernel to its knees...
* Update: Just upgraded to XP SP3 from SP2, and problem persists.
