If you don't explicitly change the lock directory and do not disable locking, the same directory should be used. I'm assuming this is all done on a single server sharing the same file system. The locks are stored in the system's default temporary directory. That's typically /tmp under UNIX/OSX and C:\WINDOWS\TEMP (I think) on Winblows.
