--------------------------------------------
I see - I wasn't aware of this issue, and I suspect the same problem might be present in other classes that log while locks are being held.
Anyway, I agree that this should be avoided in this class, how about using a framework property to disable those logs by default, like the existing ds.loglevel one?

----------------------------------------
The main issue I see with this patch is that it logs while holding locks. It prevents us from pretty much ever using external loggers. Not that this is too big of a deal, since this issue has been with us for quite a while, which is why we don't log to a Log Service if one is present, since we were getting into deadlocks.
