Unfortunately the levelII oplock implementation in 2.0.5a
has a logic bug in that it frees a semaphore twice. This
is why I'm glad Andrew persuaded me to have the feature
default to "off" in 2.0.5a :-).

I have a fix which will be in 2.0.6, please ask if you
need me to dig out the code changes for 2.0.5a.
