What I might do is create a file "mydbmlock" and then do something like this:

use Mac::Files;
FSpSetFLock $file;      #lock
FSpRstFLock $file;      #unlock

Lock it to lock it, unlock it to unlock it.  NOTE: there is a bug in
MacPerl 5.1.3r2, such that you cannot call the FSpRstFLock method directly.
Instead, you need to call "Mac::Files::FSpRstFLock" (I think that works).
