The terrifying result of having ABI compatibility with the first commercially successful system of its kind from the '80s.

Granted, they aren't doing themselves any favours with their new straight-jacket style application ABI.

These posts are getting boring.. the only thing that they're saying is: I can use ETW and to me being told that I'm smart and capable is paramount.

I can't imagine that moving the Win32k stuff back to CSRSS would help much in this case, right? Though it is still a good thing especially for terminal servers where hopefully one CSRSS process crashing just terminate the session.

I read mouse as house and was confused for the longest time.

Then why are you commenting? Kind of a crappy attitude you have there.

The post identified a problem in Windows locking behavior, and showed the process that was used to reach the conclusion.

Your comment on the other hand tells us more about you than about the person you are criticizing.

When I saw his workstation specs, I thought, thats the exact same one I have at work! Then I checked the bottom, yep, he's at Google too.

I was wondering what ETW is, and found in one of his other posts: ETW (Event Tracing for Windows).

He seems to be one of the main contributors of https://github.com/google/UIforETW

Seems to be quite useful.

About the post: tl;dr: NtGdiCloseProcess has a system-wide global lock which is used quite often e.g. during a build of Chrome which spawns a lot of processes. This problem seems to be introduced between Windows 7 and Windows 10.

I thought that there would be a solution or a fix but it seems this is not yet fixed. "This problem has been reported to Microsoft and they are investigating."

not really, I was kinda expecting the post would also contain interactions with Microsoft, leading to the resolution of the bug in update XX. The post kinda left me unsatisfied.
