I took a look at the buildbot failure reported at 
https://lab.llvm.org/buildbot/#/builders/138/builds/19309/steps/7/logs/FAIL__MLIR__async_mlir
But I don't see how it was related to the recent PR https://github.com/llvm/llvm-project/pull/159544

I note that builder 138 reported a similar failure twice in the previous 100 or so builds:
https://lab.llvm.org/buildbot/#/builders/138/builds/19224/steps/7/logs/FAIL__MLIR__async_mlir
https://lab.llvm.org/buildbot/#/builders/138/builds/19212/steps/7/logs/FAIL__MLIR__async_mlir

And I note that the latest build
https://lab.llvm.org/buildbot/#/builders/138/builds/19310 has just succeeded.
I suspect there is something inconsistent about the MLIR async test run by buildbot 138, and this is not a fault in PR159544.
