Thread is missing exit invariant failure on drcachesim.invariants test
The x86_64 tool.drcachesim.invariants has failed on the master merge a number of times in the tool.drcachesim.invariants test:
Some older ones: https://github.com/DynamoRIO/dynamorio/actions/runs/7731301531/job/21078628227 https://github.com/DynamoRIO/dynamorio/actions/runs/7732983950/job/21084129568
A few more recent ones too. https://github.com/DynamoRIO/dynamorio/actions/runs/8442624559/job/23124442264
Trace invariant failure in T27434 at ref # 373883 (0 instrs since timestamp 13351202897274636): Thread is missing exit
Locally I can reproduce:
$ ctest --repeat-until-fail 500 -R sim.invariants
Failed after 29 successes.
Also failed on AARCH64 ("aarch64-precommit (ubuntu-20-arm64-sve)") one time (so far) in #6691 (https://productionresultssa14.blob.core.windows.net/actions-results/7de917d3-3760-4c4e-8868-17a821dcbe85/workflow-job-run-aec6087b-1676-5d99-51e5-fc3628aaa01c/logs/job/job-logs.txt?rsct=text%2Fplain&se=2024-03-27T03%3A15%3A40Z&sig=4uo4KtcH6yeXG%2BApsmdkKeOQhQJNsAmoHkwgo4riuNE%3D&sp=r&spr=https&sr=b&st=2024-03-27T03%3A05%3A35Z&sv=2021-12-02).
Sometimes it also times out (tested on x86_64):
$ ctest --repeat-until-fail 500 -R sim.invariants

This keeps failing periodically on post-merge runs, which we're trying to get green. E.g., failed just now: https://github.com/DynamoRIO/dynamorio/actions/runs/8470861218/job/23209561877
