err:ntdll:RtlDeleteResource Deleting active MRSW lock, expect failure

Hi,

Does anyone know about this error?
It sometimes occurs on a Linux machine after the mmdevapi
capture tests exited, with a delay as if originating from
the server (or a service.exe).
Some capture logs sent to me contain this too.

Looking up bugzilla, you'll find this error mentioned half
a dozen times with various apps.
