I was told about 6 months ago that it was not possible to lock pages into ram so that they cannot be swapped out. But recently, I've found various references to the fact that pages can be, as they call it, "wired down". In the man pages for vm_stat, it claims that wired down pages cannot be swapped out; this is what I am looking for. Does anyone know if/how this can be done and can it be done with any program. I need this to ensure that a very high priority program will not be swapped out.

If your program is a Loadable Kernel Server, you can specify that you want it "wired down", to avoid paging. I don't know how the kernel server loader does it, though.
