21 = ERROR_NOT_READY. This launches a process through IWbemServices::ExecMethod. Likely next to impossible to figure out why this is happening without a repro and debugging IWbemServices::ExecMethod itself.

Although it's a bit fishy that one time it gave ERROR_INVALID_BLOCK - I don't know what that means.

Probably this test should either ignore these particular error codes, or retry.
