The profiler test itself passed Profilee STDOUT: PROFILER TEST PASSES, but for some reason the process isn't exiting given theres no Expected: 100\nActual:100 that is supposed to output in the test script.

This happens occasionally, and is not clear how to reproduce, I don't believe this is specific to the handles profiler test at all, but something going awry with the child process exiting.

There's some extra logging that we've added to CoreclrTestWrapperLib that didn't make it to release/9.0-staging, so for example, if the environment var for USER is not set, that might be why the crashdump couldn't be opened. @kunalspathak Do you know what's responsible for setting the USER env var?

The test timeout is not unique: #66174 #107067

Closing the profiler/handles/handles/handles.sh side of this issue.
