Thanks Edward,

I was thinking that SYS(2011) checked to see if anyone had the record locked - that could have been a fun one... I DO infact want to check if anyone has records locked. It looks like I'll need to perform a SYS(2011) to check for the current W/S's locks and include them in the result set, then attempt to lock the remaining records, and only include the failed locks in my result set.

It could be worse.
