Indeed! :)
In any case, from that man page, I don't see how you can do both of
"quiet all disk activity" and avoid the problem I mention above
(which really isn't specific to your process; modern OSs have a lot
of processes that can fire at any time to handle the exigencies of
the moment; they need to be able to run, or the system crumbles).
Right. I'll never quiet *all* disk activity; all I can hope for is to
minimize it somehow.
You could, as mentioned earlier in this thread, avoid enabling the
paging daemon. With sufficient memory, you could run a full
system, but things may start failing in strange ways without the
elasticity provided by a backing store. In case you haven't looked
in depth at the Mac OS X VM system, it's all handled by the paging
daemon. There is no path to disk (for this purpose) within the
kernel.
Right (and thanks John and Graham for the info there). I'd considered
messing about with dynamic_pager but wouldn't like to modify the boot
args nor kill it outright for very obvious reasons. I need to look
into the workings of the paging daemon some more ...
Thanks again,
