Doorbell locks are one of the neatest things brought to us in vms 4.0! I
believe they've worked properly since then. The idea is to take out an
exclusive lock on a resource, and when you get the blocking notification,
let go of it. Something like that. The notification is an AST, and lets you
know who's asking for the lock (IIRC).
My dear departed friend Alan Barr wrote a really neat series of fortran
tools which implemented this in a quite nice way; I've used these tools a
few times. I've never tried VMS::lock, however.
Best, Carl
