Expected: ".NET Long Runni" is very generic pattern that can match number of unrelated issues. I have updated it to be make it more specific.

This looks like a dupe of #107821. It seems odd that the expected name is ".NET Long Runni", do we really expect the process started by CreateDefaultProcess to have that name (which looks like that name stems from a long running task being trimmed

runtime/src/libraries/System.Private.CoreLib/src/System/Threading/Tasks/ThreadPoolTaskScheduler.cs

Line 51 in 1d69684

Name = ".NET Long Running Task"

) instead of dotnet?

All other instances of .NET Long Runni in other issues seem to be some problem with hangs/futex-internal.c when looking at callstacks in #92070, #90019, #105808, and maybe even #109630 and #106595 might have the same underlying issue.

Triage: it seems that reading a process name on Linux makes some of our tests flaky (#109630, #110643, #111460).

@jkotas has suggested in #111460 (comment) that we maybe reading it too soon. I am going to try to add a simple retry mechanism to see if it helps.
