Yup... >To me, it just seems that you almost need to prove out that your >application is likely to allow a true race condition before locking >every call. Acknowledged. My (admittedly conservative) approach is to prove that the app _doesn't_ need locking rather than the reverse. Don't get me wrong, I'm all in favour of eliminating both the extra coding burden as well as the overhead. That said, the docs seem to lean towards locking when in doubt... that and the fact I've had the whole locking religion hammered home relentlessly over the years. It may take me a while to get with the new program. ;-) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Want to reach the ColdFusion community with something they want?
