Thanks all, I don't use defer in a lot of the places to optimise and
minimise the lock time. I suppose looking at those points is probably the
safest place to start!

Start with the basics like go vet which will spot a lock being copied by value.
Then check for each place you call Lock, there is a defer statement on th next
