No. It's an application. We're starting to lay out those interfaces this
week and next. See the VSC documentation on www.eros-os.org for an idea.

Three ways:

1. You could somehow invoke your own process and receive the result into
an address space slot using an appropriate capitem_t

2. You could fetch your address space cap and walk the tree by hand to
perform the insert.

3. You could fetch your address space cap and do an insert operation
(probably not in the spec yet).

For now, option (2) would be the way to go.

Note that a lot of this stuff will quickly end up in a library.
