Description James Manning 2002-07-16 15:19:31 UTC
basically, i'd love to be able to run a command, as root is fine, to mlock the
pages of a currently running app.  Since this command would be in another
process and therefore not the same VM area (barring the strace-ish tricks) then
it seems like it can really only request that the kernel do this operation for
him, right?

There's a good # of apps that I only use on an interactive basis but take a good
chunk of memory, and it'd be nice to get them pinned so that when I come back to
them the next morning I'm not waiting "forever" for them to swap back in.

Is this already doable and I just don't see it?

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
persists.

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
