Hello,
I decided to stop lurking around, so here's my first question :
I have read the design document : it seems that it is not possible
for a task to be completely paged out, because of the pager thread.
Am I correct ?
However, there is something written about a "final pager", and the
howto in the hurd-l4 sources states :
"Then the last-resort pager in a task can run on memory in this
container, and physmem can freely unmap that memory temporarily
(for reorganization). The last-resort pager would use physmem as
its pager. This relieves the need to wire down the memory the
pager is running on."
Is this "last-resort pager" the same thing ? Does it mean that a
task can have more than one pager ? Or that each pager should
itself have a (possibly non user-defined, system-fallback) pager ?
