[Bug 45546] Magic The Gathering Arena updater: Unity fork of Mono-runtime reports 'Fatal error in gc, GetThreadContext failed' ( suspension of Mono-managed threads sometimes exceed 100ms)

Hello Anton,

I suggest you read up some comments and study Wine source code to learn how
thread suspension is implemented in Wine.
If you have doubts about the current conclusion please provide a detailed
(timing) analysis of the MTGA updater/Mono-Runtime on your own, backing
whatever alternative conclusion you come to. Waiting for it ...

Its also not clear why would GetThreadContext even be able to timeout with
ACCESS_DENIED in the first place

You've got to be kidding...
There are source code snippets provided in my comment.
