Locking sav files [message #55284]

Hi,

I've been experimenting with locking sav files.

* A process should not interrupt another processes attempt to modify a
sav file.
* Each process deals with copies of their sav files until they call
"commit"
* If a process if blocked from committing its sav files then it should
enter a queue (FIFO)
* A process will wait on the queue until it can commit or there is a
timeout
* There is a maximum number of active processes (default: 8) and size
of the commit queue (default: 4)
* The system must work equally well regardless of backing store
(NTFS,FAT32,Samba,NFS)

The source code is available at http://barnett.id.au/idl/ .

Any thoughts or comments?

Robbie
