Yes, I am not too worried about the optimizer at this point.

fcntl-locking even without contention is just plain slow.  Don't you 
think having a local copy would speed things up?  It may not, but my 
guess is that especially with heavy user-cache usage, lock contention is 
an issue.  Remember that we hold the lock for the duration of the memcpy 
on a user cache hit.

Yeah, for TSRM I guess we don't gain anything, so I'd say disable it in 
TSRM mode.  Nobody sane runs TSRM anyway.
