There was a problem hiding this comment.
That LGTM.
However, if you're trying to run crossgen2 compiles without excessively slow stress modes, you might also want to save/restore COMPlus_HeapVerify, and maybe COMPlus_ReadyToRun. There are other things that also run slow, like COMPlus_JITMinOpts, but perhaps not enough to worry about it.

I have a first reasonable run at
https://dev.azure.com/dnceng/public/_build/results?buildId=746207&view=results
after I fixed the CLRTest.Crossgen2.targets script to suppress the GC stress mode for the duration of Crossgen2 compilation, otherwise it seems to me that the "dotnet" command used to run Crossgen2 silently picks up the COMPlus variable and runs Crossgen2 itself in GC stress mode, causing impractical compilation times and work item timeouts left and right. The script modification hopefully also
Fixes: #39933
Thanks
