I hate to be a skeptic, but releaseExclusiveAccess sanity checks 
itself against an internal reference count. Extraneous releases are 
essentially just no-ops. The only way it would cause harm is if the 
object upon which it was been invoked was invalid. Which makes me 
wonder...

Do you ever release a DRDevice? Its unlikely you would have to, since 
all the methods to get them from DR are get and not copy or create. 
Releasing DRDevices out from under DR is a very common mistake, and 
would cause this symptom.
