hi Greg, yep these mechanisms exist, this is the first things that you
implement when you write a lock system no matter on what: islockable

try to understand, what you do (if you use a lck object (locked))
if your lock object has been created, a lock has been aquired
when you create a lock object, the lock system test it for you
