how to check if a record lock is in place

does anyone know how i can check if a record has a lock in place before I attempt to lock the record?

Eg

<-- check here if the specific record is already locked.

if not locked

MyModel.lock!

else

skip to the next model.

thanks

I do not know whether this can be done, but I think that even if it
could it would not be safe. In the gap between testing the lock and
attempting to lock it someone else could lock it themselves so you
would still have to deal with the consequences of attempting to lock
an already locked record.
